If Kerbal Space Program 2 (KSP2) is crashing on your PC, first identify whether the game actually closes or freezes—or whether it is starting slowly or running at a poor framerate. Those symptoms call for different checks, and the available official guidance does not establish a universal crash fix. Work through the reversible checks below, noting where the failure occurs and whether it repeats.
Steam currently lists KSP2 as an Early Access game and displays a notice that the last developer update was over two years ago; that is a store-page status note, not confirmation that support has ended. Steam’s KSP2 listing provides the current system requirements and support contact.
1. Identify what “crashing” means in your case
Record what happens and when. A process that closes, a game that stops responding, a failure during startup, and a long or slow load are different symptoms. Poor framerate during play is different again. Note the exact stage—launch, loading, a particular screen, or gameplay—and copy any error message shown. This helps you avoid applying a performance suggestion to a genuine crash.
- Closes: KSP2 exits to the desktop or its launcher.
- Freezes: the game remains open but stops responding.
- Fails on launch or while loading: it exits or becomes unresponsive before gameplay.
- Runs slowly: the game remains active but has low framerate or long load times.
2. Compare your PC with Steam’s listed requirements
Check your Windows edition, memory, graphics card, and available storage against Steam’s KSP2 system requirements. The listing specifies a 64-bit processor and operating system.
#1 Best Overall
- Ultra-Portable: Slim, portable, and light weight allowing you to protect your investment wherever you go
- Ergonomic Comfort: Doubles as an ergonomic stand with two adjustable height settings
- Optimized for Laptop Carrying: The metal mesh provides your laptop with a stable laptop carrying surface
- Ultra-Quiet Fans: Three ultra-quiet fans create a noise-free environment for you
- Extra Usb Ports: Extra USB port and power switch design allows for connecting more USB devices. Warm Tips: The packaged cable is USB to USB connection. Type C connection devices need to prepare an Type C to USB adapter
| Requirement tier | Operating system | Memory | Graphics examples | Storage |
|---|---|---|---|---|
| Minimum | Windows 10 64-bit | 12 GB RAM | NVIDIA RTX 2060 with 6 GB VRAM, NVIDIA GTX 1070 Ti with 8 GB VRAM, or AMD Radeon 5600 XT with 6 GB VRAM | 45 GB |
| Recommended | Not stated separately in Steam’s listing | 16 GB RAM | NVIDIA GeForce RTX 3080 or AMD Radeon RX 6800 XT | 60 GB |
These are the figures in Steam’s current listing, accessed in 2026. Meeting the minimum or recommended requirements does not guarantee crash-free play, and a mismatch alone does not prove what caused a particular crash. Treat this as a compatibility check, not a reason to buy hardware without evidence that your system is below the listed requirements.
3. Restart once and see whether the failure repeats
Restart the PC, open the game again, and note whether it fails at the same point. This is basic PC troubleshooting, not a KSP2-verified cure. A repeatable failure at the same screen or action is useful information to include if you contact support.
Rank #2
- Whisper-Quiet Operation: Enjoy a noise-free and interference-free environment with super quiet fans, allowing you to focus on your work or entertainment without distractions.
- Enhanced Cooling Performance: The laptop cooling pad features 5 built-in fans (big fan: 4.72-inch, small fans: 2.76-inch), all with blue LEDs. 2 On/Off switches enable simultaneous control of all 5 fans and LEDs. Simply press the switch to select 1 fan working, 4 fans working, or all 5 working together.
- Dual USB Hub: With a built-in dual USB hub, the laptop fan enables you to connect additional USB devices to your laptop, providing extra connectivity options for your peripherals. Warm tips: The packaged cable is a USB-to-USB connection. Type C connection devices require a Type C to USB adapter.
- Ergonomic Design: The laptop cooling stand also serves as an ergonomic stand, offering 6 adjustable height settings that enable you to customize the angle for optimal comfort during gaming, movie watching, or working for extended periods. Ideal gift for both the back-to-school season and Father's Day.
- Secure and Universal Compatibility: Designed with 2 stoppers on the front surface, this laptop cooler prevents laptops from slipping and keeps 12-17 inch laptops—including Apple Macbook Pro Air, HP, Alienware, Dell, ASUS, and more—cool and secure during use.
4. Check the game version and repair its files if your launcher offers that option
Check that the launcher you use shows the installed game as up to date. If it provides a file-integrity or repair option, run it and then retry the same action. The official materials cited here do not provide a current KSP2-specific procedure for file verification, so treat this as general launcher troubleshooting rather than a confirmed KSP2 remedy.
5. Test without mods, if you use them
If mods are installed, temporarily launch the game without them and check whether the same failure occurs. Preserve your saves and configuration before changing files, and avoid deleting data as part of this test. This is an isolation check: the official materials cited here do not establish that mods are responsible for your crash.

6. Lower graphics quality only if loading performance is the problem
If the game is slow during initial loading or you are trying to improve framerate, try a lower graphics-quality setting. In its February 24, 2023 launch notes, the KSP2 team recommended changing graphics quality for initial-load framerate problems. That is historical performance advice, not a documented fix for a game that closes or freezes. Read the February 24, 2023 launch notes.
7. Simplify an engine-heavy craft if framerate drops during play
If poor framerate happens with a craft that has many engines drawing from one shared fuel source, test a simpler craft with fewer engines. The same February 24, 2023 launch notes suggested using fewer, higher-performance engines for framerate trouble. This does not establish a general crash cause or cure; use the check only when the symptom is performance-related.

8. Contact support about persistent or urgent crashes
For a crash, freeze, or game-breaking issue that persists, send support the details needed to distinguish your case:
- Where the failure occurs and what you were doing immediately before it.
- The exact error message, if one appears.
- Your Windows version and PC hardware, especially RAM and GPU.
- The installed game version and whether the failure repeats.
- Whether you tested without mods, if applicable.
The February 24, 2023 launch notes direct players with urgent crashes, freezes, or other game-breaking issues to Private Division Customer Support. Steam’s current listing gives the support email as [email protected]. The launch notes document one specific historical crash—a crash when returning to the main menu from the Vehicle Assembly Building—and say it was fixed in an update; that does not identify the cause of an unrelated crash. See the official update notes.
