Should have been fixed by #7482. Please comment if that's not the case and I will reopen this issue. Thank you.

The bug is still there, but I managed to how EXACTLY why :
The background player crashes when the first video of a playlist is not available (Hidden, Downed, blocked in your country, copystriked...) for whatever reason.

If the playlist is manually started to any video that is available, the bug does not occur.

@LeducBastien If this is still happening in the APK you got from #7482, then please add your comment there.

Still happens in 0.21.16, exact same logs, only with peertube though. When i exit the newpipe app since i want audio to play in background it crashes but doesn't give me a log. Clicking on 'popup' button in the peertube video gave me this exact crash log tho
