What happened? Did the bug go away?

[dragnev-dev]

No, I was on mobile. I'm not familiar with the GitHub UI so I mistakenly thought what would be a button to be a drop-down.

[opusforlife2]

Okay. Please post a screen record of the crash.

Thanks! Does this happen only with channels? Or also feeds, playlists, etc.?

Ok so which scenarios also trigger the bug. The OP scenario is you long press a video, tap download, then you navigate to a channel before the prompt for the download appears on the screen. Furthermore, cases which trigger the crash after requesting a download are:

• [x] crashes when navigating to a playlist;
• [x] crashes when navigating to a different screen through the burger button side menu (feeds, settings...);
• [x] crashes when navigating to a channel through long-press on a video "Show channel details";
• [x] if you request a download on a video from trending feed (no search applied), then calling a search and navigating to search, it crashes;
• [ ] doesn't crash when navigating to a feed through the tabs in the top navigation;
• [ ] doesn't crash when requesting video long-press actions "Start playing in a popup", "Add to playlist", "Share";
• [ ] doesn't crash when navigating to a different service (SoundCloud, BandCamp...).

Ok, so it happens when Newpipe opens an entirely new fragment. Thanks for testing!

Yes, it is related to downloader see #3163 & it is old one https://github.com/TeamNewPipe/NewPipe/issues?q=is%3Aissue+Can+not+perform+this+action+after+onSaveInstanceState+

May I have this issue assigned to me? I can try to fix it.

@elvakang You can do so, but there's a low probability of them being reviewed any time soon. If you're still okay with that, please go ahead!
