Roon loading forever


When I add to the library an album from it takes minutes lately but today it loads forever and I have a circle rotating in the upper right of the screen (also on remote)…

If I click on that rotate icon I get "Added music to library: 77 tracks, 77 added, 4 identified.

It’s so since more than one hour, tried to reboot Roon and PC too.

It also didn’t load some covers of albums from Tidal that I lately added to my library (no issues on Tidal app instead).
