We have gone through quite a bit of settings to make sure nothing is out of place, including project settings → physics
done extensive testing on disabling systems to try to narrow something down.
We even found 2 threads with this same exact crash report “except access code was different”
both of their fixes were Deleting a BSP brush on the level and the other had 2D graphics checked in project settings.
Neither of these are our issue.
please help q.q…
