Hi, whenever I try to press play the engine crashes. The first time I got the error is when I tried packaging the menu map but then I tried also to package other maps and I got the same problems. Today when I tried to press the play button it’s started crashing with the error “Runnable thread StallDetectorThread crashed.”
I tried to compile all blueprints from the command prompt but I didn’t get any errors.
This is the crash log:
Assertion failed: Child [File:D:/build/++UE5/Sync/Engine/Source/Runtime/CoreUObject/Private/UObject/UObjectGlobals.cpp] [Line: 3308] NewObject called with a nullptr class object
