Thank you for your help. I will check the settings tomorrow but I don't think that I have changed anything from the standard.
Another thing that you may have noticed from the log : I use the Emby addon. Therefore, Kodi is not the one that will get the database information, it's the Emby server that manages this. Could it be related ?

I don't know. I've never used Emby. That said, the log looked fine to me except for the problem of the incomplete path to the local artist folder. And that is set through settings, not the music database.
