Unreal Engine 4.25 released!

You could try next to disable Event Driven Loader, perhaps the error gives better clues.
There is a user reporting issues with physics, perhaps your project crashes because of a similar issue. The empty map loads, because the clean DefaultEngine.ini no longer contains your configurated default maps.

No luck with disabling Event Driven Loader either sadly. Still get the error code

Unhandled Exception: EXCEPTION_ACCESS_VIOLATION reading address 0x00000038

Tried to search for others with the same error but not finding anything relevant or related to 4.25.4.
