The game launches, displays the opening cutscene correctly, and the start menu is fully navigable. All options work without issues. However, when selecting ‘New Game’, the following errors appear and the game crashes
Pure virtual function being called while application was running (GIsRunning == 1)
LowLevelFatalError [File:D:\build\++UE5\Sync\Engine\Source\Runtime\Core\Private\Windows\WindowsPlatformMisc.cpp] [Line: 439]

UPDATE 1:
If you set the compatibility mode to Windows 8 in the properties, the game starts without any issues
UPDATE 2:
When you’re playing and save your game on the Mysterious Island, then exit to the main menu and try to load the save again, the following error is displayed and the game crash:
Pure virtual function being called while application was running (GIsRunning == 1).

If you close everything and try to reload the game, the error is still present. Rebooting the PC doesn’t fix it either.
