[YouTube] Fix for HTTP error 403 when starting videos: TeamNewPipe/NewPipeExtractor#1191
Fix crash in MediaSessionPlayerUi while destroying player #11261
Note that this does not fix 403 err...
Bear in mind that in-video ads that Google is experimenting with will still cause 403 errors. There is another bug report for that. However, this fixes most playback issues.
Wonderful news. I just updated and it's working again. YouTube is so far down the enshittification tunnel that it's only a matter of time until something like this gets rolled out again. I really want Peertube to be the one, but there's just not that many people using it. I've done away with reddit and Twitter and now much prefer Lemmy and Mastadon, but YouTube is harder to kick.
