Hello, I suddenly started to have a fatal error when changing the level on a packed game. Literally before this packing, I packed again and everything worked. Now for the second day I am looking for a solution. In other games created on UE4, this error appeared if the user processor did not support the SSE 4.1 instruction, my ryzen 5 3600 definitely supports it, I tried to give the packaged project to another computer on intel - the same problem. I tried to change the “List of cards for packaging” (remove everything and add it again). Reinstall VC_redist C++ and unreal engine too. Maybe someone has encountered something like this? The project has version 4.25 uses plugins Advanced Session, Power IK, AVS. OH! and it’s in the clipboard:
I understand. Node:“automation wait on lodaing” in my character break game)
I hope its help to someone.
But its still fatal error when another player connecting to me 
Fatal error!
