First off, I apologize if this has been asked, I don't believe I saw it during my search.
I'll start by saying everything "was" going fine. I literally was adding ROMS for several different systems, downloading the box art etc. Once completed, I got the XX ROMS added successfully. Great! Well literally (on the drop of a dime - meaning NOTHING changed/happened on my end. Talking a matter of minutes between a successful batch of adding ROMS to the next) the NEXT attempt I would get an error message stating " An error occurred while attempting to search local metadata database for ROM file...../// etc.) - Would you like to keep the imported games despite these errors? I can say no, or IF I say YES, THEN I Get a crash/error (see attached screenshot) and it closes the program. Like I said I had done thousands of ROMS no issues and then THIS came out of NOWHERE. SO ODD.
PS - I tried other types of consoles/ROMS to see if that was the issue - and it happens regardless of the ROMS/FIles.
