I love this add-on but I'm having intermittent problems. I use CoreELEC as my frontend to connect Kodi to my music collection over the network. The machine where music and the Artist Information folder is stored is a windows 10 computer. Every now and then, Artist Slideshow chokes and then keeps displaying art for the same artist until I reboot. Log shows an error like this:

Code:

The network access is via SMB, permissions are those of an admin user on the windows machine. Correct access data is saved in password.xml.

Now, I've had a look at this specific file the log entry is complaining about. It does exist and was written or changed on 2020-04-02 23:28. I'm unsure why the log complains about the file not existing. Is it possible that Kodi or your add-on attempted to write/change the file the same time it was accessed while playback happened? In that case I guess it would have been locked.

Additional configuration info, Add-on "Storage" is configured to
Store artist images in => Kodi artist information folder
Store artist information in => Custom location
- Custom location => Path to Kodi information folder

If that configuration is invalid because of potential lockups it should probably say so in the config screen. Thanks for looking into it!
