Shipped game crashes with error "Pure virtual function being called while application was running (GIsRunning == 1)"

Hi
I am building Paper2d pixelart 2d Game using Blueprints only. In PIE project works perfectly. But when fired as a standalone game or when being run as shipped game it crashes with error “Pure virtual function being called while application was running (GIsRunning == 1)”. It is happening during loading new level with Blueprint node “OpenLevel (by Name)”. I attached a log documenting error I encountered to.
Also randomly game crashes at startup with message box saying “Fatal Error” and after clicking OK button it closes down.
Both above issues happens during running game in Windows 11. In Windows 10 the same game build works without any errors. Does anybody experienced similar problem and know how to solve it? I use Unreal Engine 5.1.0.
