rekordbox - unable to create / edit intelligent list, application crush

Hi, I come across a problem with my REKORDBOX 6.5.2 after updating from 6.5.1:

I am unable to edit or create a new intelligent List... when I am trying to do that - REKORDBOX stuck and then crush... 

I tried to downgrade the versions and it didn't helped. 

Anyone come across this issue?  

Any suggestions what I can do (I don't want to re-install since I afraid I will lost all my data (tags, comments etc').
