Spotify Web Player error

[prpjzz]

I have a rather unpleasant problem: When I turn on Spotify Web and run a song, it says like the picture below, which happens in about four or five songs, and when I get to the sixth track in the playlist, it's normal.

I don't know if this error was caused by Wideline, but if I tried to erase Spotify's data, the error would still happen.




Here's a description video for this error. Of course I tried to shut down all the extensions, and it looks like the error is still happening.

If you can play the video here, your Widevine component is fine.
But this is an old issue between Netflix/Spotify and non-mainstream browsers.
You may need to use Chrome/Firefox/Edge for them, or use their apps.
