MacOS, Last.fm covers stopped working

[frankiesimon]

Describe the bug
I have integrations with Spotify and Last.fm set up. When I play a song on Spotify the cover art is shown. When I play a song on YouTube and confirm it's properly scrobbled in Last.fm, I get just the title and artist but not the cover art. This used to work up until a few weeks ago, maybe a little longer.

To Reproduce
Steps to reproduce the behavior:

1. Play any song on Spotify.
2. Confirm the proper title / artist / album art is generated in the output file.
3. Play a song on YouTube (using any last.fm-friendly browser integration)
4. Confirm the song got "scrobbled" on your last.fm profile
5. Check the files for title / artist / album art.

Expected behavior
I'd expect the cover file to be the correct image

Screenshots
Spotify works as expected:

YouTube based scrobbled song, title and artist got updated correctly but the cover image is just the temp 0-bytes file.

Log
Looking at the log it seems that this message repeats when the issue happens:

19:34:35.518: [tuna] Couldn't fetch file from  to /Users/frankie/NowPlaying/cover.png.tmp, curl error: URL using bad/illegal format or missing URL (3)

Can you enable this option in the tuna stetting dialog, restart OBS, play the song with the last.fm scrobbling enabled and then check http://localhost:1608 in your browser and paste the output here?
