Bizarrely, none of my rollbacks on my version control fix a corrupt uproject. UE just crashes after the splash screen. Other things I’ve tried:
-
tried deleting cache folders (deriveddatacache, intermediate, saved)
-
tried verifying engine
-
other uprojects still open fine
-
Last night, I updated my AMD gpu’s driver (had to force a restart mid-session).
-
resetting the default map in the gameengine.ini config lets me actually briefly open UE– but then it crashes with the same error.

Here’s a pastebin link of the log and a snippet of it:
