Editor crashes when selecting GameMode

On some computers in some levels we have a crash when clicking GameMode Override ComboBox in World Settings Menu. It opens an Overlay with Text “rebuilding class hierarchy” and crashes immediatly but no crash reporter opens. The MiniDump with debug build is in attachment.

Selecting GameMode in Blueprint Menu don’t crashes.
