If Mount & Blade II: Bannerlord keeps crashing on PS5, first check that the game is fully updated—and, if you own War Sails, that its update has finished too. TaleWorlds says launching before both downloads are updated can cause a crash. Then work through the standard PS5 troubleshooting steps below. They may help, but no official source confirms one fix for every Bannerlord crash.

Start with the game and its updates

1. Check for a Bannerlord update

On your PS5, highlight Bannerlord, press the options button, and choose Check for Update if that option is available. Compare the installed version with the latest release shown on the console and TaleWorlds’ official patch notes. The latest notes located for this article are for v1.4.7 and are dated July 8, 2026; check TaleWorlds for any newer release before treating that as the current version.

2. If you own War Sails, make sure both updates have finished

TaleWorlds warns that Bannerlord and the War Sails expansion can update at different times. Launching before both are updated can crash the game. Check the PS5 Downloads/Uploads queue and wait until both downloads or updates are complete before launching.

3. If the game and expansion were out of sync, follow the console-compatible remedy

TaleWorlds advises verifying game files for the update-mismatch problem. PS5 does not provide a Steam-style “verify files” button, so do not look for one in the console menus. Make sure the game and expansion are fully updated; if the crash continues, use the reinstall option below or contact support.

4. Check whether the crash matches a situation addressed in the patch notes

TaleWorlds’ v1.4.7 notes list fixes for crashes after exiting a conversation, attacking a raiding party on the campaign map, defending a village during a raid when there is no militia, cloth simulation, battle memory ordering, and AI behaviour. If your crash happens in one of these situations, install the latest available update and see whether the issue persists. The notes describe fixes, not a guarantee that every similar crash is resolved on every platform.

Try standard PS5 troubleshooting

The following are PlayStation’s general game-start troubleshooting actions, not Bannerlord-specific diagnoses. Follow them in order, stopping if the problem is resolved.

5. Restart the PS5

Restart the console from the power menu, then launch the game again. A restart is a quick, low-impact first maintenance step in PlayStation’s game troubleshooting guidance.

6. Restore licenses

If you own a digital copy, restore licenses through Settings > Users and Accounts > Other > Restore Licenses. This is a general license troubleshooting step; it does not establish that a license problem caused a crash.

8. Delete and redownload the game

If the crash continues, delete the installed game and download it again from your library or the PlayStation Store. Use a wired internet connection for the download if possible. This is a general PS5 troubleshooting step, not confirmation that the installed game files are the cause. Do not delete saved data as a routine part of reinstalling.

9. Update PS5 system software

Safe Mode changes system maintenance state, so select the intended option carefully; do not choose Reset PS5 or reinstall system software as an early crash fix.

If Bannerlord still crashes

Keep a short record before contacting support: note any PS5 error code, what you were doing immediately before the crash, and the steps that reliably reproduce it. PlayStation requests these details when players contact support. You can also use the PLAION Bannerlord Helpcenter to look for an existing solution or submit a support request. The official material does not establish that every current PS5 crash is fixed or identify one cause common to all crashes.
