Rekordbox v6 doesn't work

I am having recently problem with the track analyser. I thought if I updated to v6 it would solve the problem, but no luck so far. After updating to Rekordbox v6 it still doesn't work. My library has converted succesfully. But I can't analyze or set hot cues. As well for existing as for new songs.

When I start I get the pop-up: "Some tracks in the Collection were analyzed by an older version of rekordbox. To show a new waveform, click [Add New Analysis Data] in the drop-down menu.

I have already analyzed all songs, but it doesnot help.

When I double click a song to load in track analyser I get the message: "Lyrics acquisition failed".

By the way I have the free subscription plan as I only use Rekordbox for music management.
