Constant Crashing in 5.3 EXCEPTION_ACCESS_VIOLATION reading address 0xfffffffffffff

Hello,

I’ve been going through and learning unreal engine 5, but starting in the past few days every 30 minutes or so UE5 crashes and I get

Unhandled Exception: EXCEPTION_ACCESS_VIOLATION reading address 0xffffffffffffffff

Everywhere I’ve looked I’ve seen similar errors, but different codes, not 0xfffffffffffffff.
Does anyone know what is causing this problem? I’m near wits end.

Thanks

Same problem.

Latest nvidia driver (RTX 4080 and 5950x + 64gb ddr4)

EXCEPTION_ACCESS_VIOLATION reading address 0xffffffffffffffff

Same problem with an RTX 4090

Welcome to the Unreal Engine Community Forum. With the Exception Access Violation error, I’d start by trying to run it in DirectX 11 rather than 12. Test it with Dx11 and post back here with what occurs. (Some times this can resolve the problem. Other times you may get a different error. But, in either case it’ll eliminate some possible causes and help provide us a path forward to fixing it) I hope this helps!
