Empty uTool after auto updating & import crashes

Severe problems

Dear CS,

We have been using two uTrack 24 machines for half a year now in our tour.
Generally the run fine, just some issues and crashed, but now hell broke loose:

After starting up the uTool app the program reported something in a splash screen about an update.
After OK-ing the screen I found it had been updated to 2.0.34 from 2.0.32 and – more severe – there were no songs, no playlists and no audio listed. Everything was empty.
A big shocker cause we needed to edit some playlists for our show.

All files were still at the same place on our drives. All settings were OK.
What happened???

After trying to restore our playlists and audio by importing from the currently in use USB3 flash drives, the program crashes after a few minutes of importing or within a moment at the second attempt. After installing the program on another Mac it also crashes at importing. Same after reinstalling the old 2.0.32 version.
What is wrong?

I cannot edit the playlist now and will be forced to remake all playlists and all songs again. This is a major setback and very time consuming in this stage of our tour.

Is there another way to import or get the playlists and songs back again?

Thanks.

Kind regards,
Mike Hageman,
