If Destiny 2 keeps crashing on your PC, check Bungie’s current known issues first, then work through Steam, Windows, and game-file troubleshooting in order. These steps address common causes, but none is a guaranteed fix; use the hardware-specific and advanced options only when they apply.
How to fix Destiny 2 crashes on Steam or PC
-
Check Bungie’s known issues
Start with Bungie’s known-issues page to see whether a current problem might explain what you are experiencing. The list is not exhaustive. When reviewed, it included an investigation into Steam frame hitches or performance drops after Update 9.7.0.2 and showed a last-updated date of July 7, 2026. Check the page for newer information before treating a crash as a problem unique to your PC.
-
Install available Windows updates
Bungie’s Steam troubleshooting guide recommends keeping Windows updated. This is general PC maintenance, not a promise that an update will stop every crash.
-
Update your graphics driver
Install available graphics-driver updates as Bungie recommends. If the crashing began immediately after a driver change, note the driver change and timing; Bungie’s reviewed guidance does not specify a universal rollback procedure.

Clear Steam’s download cache
Bungie lists clearing the download cache as an option for Steam or Destiny 2 problems, including an update that is not showing up. In Steam, open Steam > Settings > Downloads > Clear Download Cache. Steam may ask you to sign in again afterward.

-
Verify Destiny 2’s installed files
In Steam, open Library, right-click Destiny 2, and choose Properties > Installed Files > Verify integrity of game files. Let the process finish before launching the game. Bungie prescribes this for corrupted files associated with the MARMOT error; it is also a sensible file-check step when game files may be damaged. See Bungie’s MARMOT instructions.
-
Choose the discrete GPU on affected laptops
This applies to a specific configuration, not all crashes: Bungie warns that laptops with Intel 12th-generation Iris integrated graphics may crash in high-demand environments. Its mitigation is to select the discrete GPU for Destiny 2 in Windows: open Settings > System > Display > Graphics Settings, select Destiny 2, choose Options, and set it to High performance. Bungie’s known-issues page describes this compatibility case.

Reset CVARS only if configuration may be the cause
If the problem appears tied to Destiny 2’s settings, Bungie recommends deleting the game’s CVARS.xml configuration file. Find it in
UsersUSER_NAMEAppDataRoamingBungieDestinyPCprefs, replacingUSER_NAMEwith your Windows account name. The game creates a fresh file the next time it launches, and custom settings revert to defaults. This is not a routine first step if you want to preserve your current configuration. -
Use advanced MARMOT cleanup only for persistent file corruption
Bungie’s advanced MARMOT procedure is error-specific and more disruptive than a standard verification. Close Destiny 2, delete the files in the Destiny 2 installation folder except the
packagesfolder, then verify the game files through Steam using the steps above. Bungie says to reinstall if the issue persists. Do not use this as the first response to an unexplained crash.Rank #4

Report an unresolved crash to Bungie
If the steps above do not help, post in the Destiny 2 PC Support forums. Include that you play on Steam, any error code, what was happening when the game crashed, and which troubleshooting steps you have already tried.
Is Destiny 2 supported on Steam Deck?
Bungie says Destiny 2 is not supported on Steam Deck running SteamOS or through Steam Play’s Proton. Its Steam guide warns that attempts to bypass this incompatibility without Windows may result in a game ban. Do not treat Proton workarounds as a crash fix; consult Bungie’s Steam guide for the compatibility boundary.
