Have you tried the common trouble-shooting steps for console issues already? I'd assume so, but worth a shot trying if you haven't already.
1. Clear the Xbox system cache
Temporary system files can corrupt and cause crashes in certain games.
- Hold the power button for 10 seconds to fully shut down.
- Unplug for 1 minute.
- Restart normally.
2. Delete the game’s reserved space
Corrupt reserved space (game-specific cache files) is a frequent cause of crashes.
- Go to My Games & Apps → Battlefield 6 → Manage Game
- Select Saved Data → Reserved Space → Clear Reserved Space
(This does not delete your cloud saves.)
3. Reinstall the game
If a file became corrupted during an update or beta patch, only a clean reinstall fixes it.
- Uninstall Battlefield 6
- Restart console
- Reinstall fresh
