Unreal Engine 5.6.1 is intermittently crashing when I try to open performance settings or opening a game level. This problem exists for 5.6.0, as I initially had this problem on 5.6.0 and updated to 5.6.1 to try to resolve the issue. This problem occurs on different projects as well, as this crash occurred on a brand-new Blank project as well as a development project. I have not had these crashes up until today, 5.6.0 and prior versions have typically worked well on my system until today.

Attempted Solutions:

Rebooted computer

Updated from 5.6.0 to 5.6.1

Verified 5.6.1 installation using Epic Games Launcher (5.6.0 had a greyed-out Verify button, so I could not verify 5.6.0’s installation for some reason.)

Searched online, found potential fixes on this forum thread

Completely uninstalled and reinstalled 5.6.1

Deleted cache located in AppData/Local and allowed 5.6.1 to regenerate cache by launching Unreal again

Combined the last two solutions at the same time (deleted both cache and 5.6.1 installation, then reinstalled)

None of the above solutions have fixed my Unreal crashes. The attached link above shows the solution was replacing a corrupted asset, but if that is the case, how do I find and replace said asset(s)? Several assets were corrupted when I attempted to re-organize folders a couple weeks or so back, but no crashes had yet occurred until today.

I would appreciate any help!
