PC - Getting Fatal Error On Debug Build, But Not For Shipping Build

Using UE5.1, got a strange fatal error showing on project startup recently.

"Unhandled Exception: EXCEPTION_ACCESS_VIOLATION reading address 0xffffffffffffffff "

kernel32
ntdll"

After the message it automatically shut down the game.
The final shipping building seems perfectly fine, error only presents if I packaged a debug/development build.

Any ideas what could cause the error?
I’m really scratching my head for this one.

Thank you very much!

Additionally, the crash log file has this showing:
