My Question or Issue

I am able to download songs and playlists just fine, but going offline and playing the songs is... unstable, to say the least.

• Clicking on any playlist/album results in a "Something Went Wrong" error
• Clicking on the "Home" button also shows this error at first, but clicking "Reload Page" actually results in some things showing up (the 7 last played items)
  • Hovering over any item and clicking "Play" plays the item just fine. The player is fully functional and the queue works
• Trying to play a downloaded item from the "Your Library" section at the left side does not work. The player just gets cleared when clicking on the play button if hovering over an item with the cursor.

I have also tested this in several environments:

• Ubuntu 22.10 / Debian 12 VM -- All the issues are there
• Windows 10 VM -- All offline functionality is there, no issues
• (Android 12 -- No issues)

It may be something with the versions, the version in the APT repository and on flathub right now is 1.2.31.1205.g4d59ad7c while the version on Windows is 1.2.34.783.g923721d9, so several versions ahead.
