So long story short, the majority of the time that I try to launch into my game map from the main menu (using the Open Level node) in a packaged build, I get this error:
Pure virtual function being called while application was running (GIsRunning == 1)
Fatal error: [File:D:\build\++UE5\Sync\Engine\Source\Runtime\Core\Private\Windows\WindowsPlatformMisc.cpp] [Line: 439]

Crash in runnable thread Foreground Worker #0
I’ve looked through the crash log & callstack from the dmp file but it doesn’t seem to tell me anything of use. I also looked through heaps of forum posts about others getting the same error, but it seems the error could be a million different things and isn’t a simple one solution problem, unfortunately.
I’ve been trying to fix this all week with no luck, so any help would be massively appreciated! Thank you in advance!
