Actors and characters not spawn

Hello, UE just stop to spawn any characters, actors, also player character. Trying to spawn player char as “player start” also give no results. Manualy added actors/characters also not appearing in level start.

Compiler give no errors. Debug messager give “Access none” runtime error for any actors and characters in level. Empty level give same access none error if i trying to “GetPlayerCharacter”. Level loading normal, but instead player there “spectator mode”

How can i fix it?

Update: any widgets also not spawning.
