Problem with actors

Hello, I have a problem with actor blueprint, so when I want to extract a project to the desktop (package project) it detects errors and I do not want to unpack. There are 2 actors are wrong glitched and can’t be removed. You can not open them and switch to the game, because unreal engine 4 crashed. Crash message:


You do not have any debugging symbols required to display the callstack for this crash.

Help me please.
