Hi there @TannerM_TTV

Welcome to the Unreal Engine Forum! Were you able to get the crash resolved? If not, could you provide your system specs and the crash log for me? I’d be happy to take a peek!

This is the crash report from UEFN. Don’t know what to do!

Unhandled Exception: EXCEPTION_ACCESS_VIOLATION reading address 0x0000050bb4f810dc

System Specs:
I9-13900k

Does it show any lines below “Unhandled Exception: EXCEPTION_ACCESS_VIOLATION reading address 0x0000050bb4f810dc” by chance?

Are you running any plugins at all? If so, try disabling them and running to see if it still crashes.
