Summary0004451: Noesis Studio beta plugin - Editor crash on launch when a blueprint listed in Studio Data Classes has been deleted
Description

I am using the beta UnIf i happen to delete a blueprint class that is listed in Studio Data classes. I can't launch the editor anymore and the only solution I found is to manually edit DefaultEngine.ini and remove the problem line.

Here is the crash Stacktrace : 

Unhandled Exception: EXCEPTION_ACCESS_VIOLATION reading address 0x0000000000000038
