Roon not able to scan all my files

Mac mini set up with sub share on my time capsule.

Roon suddenly is not able to put each album in roon . This was not a problem two weeks ago, but now I only get in a part of the albums… It is scanning approx 13000 albums, but after approx 7-8000 imported, roon stops importing the rest…

This suddenly happened, don’t know why. Just formatted and did a clean install of my Mac and roon but this did not solve it.

Please help
