Enqueueing videos quickly crashes the app in version 0.21.13

[estesi]

Checklist

• I am using the latest version - 0.21.13
• I checked, but didn't find any duplicates (open OR closed) of this issue in the repo.
• I have read the contribution guidelines given at https://github.com/TeamNewPipe/NewPipe/blob/HEAD/.github/CONTRIBUTING.md.
• This issue contains only one bug. I will open one issue for every bug report I want to file.

Steps to reproduce the bug

1. Start NewPipe
2. Long press any video to trigger the actions menu and select "start playing in a popup" or "start playing in the background"
3. While the first video is still being added to the playback queue and it hasn't started playing (hourglass icon displayed), long press another video or even the same one

Actual behavior

Before the actions menu is triggered for the second video, the app crashes

Expected behavior

I expect to be able to enqueue videos quickly and not wait for the first one to load fully before I can do the former action.

I was able to reproduce the crash on a different phone running Android 7.0.

Also some steps to reproduce from #7310

I have the same error. My steps to reproduce:

• Open a "What's new" tab
• Hold a finger on the second from the top video in the list and select "start playing in the background".
• Not waiting when the video starts playing, hold the finger on the topmost video in the list.
• App crashes.

I noticed the same problem on Android 11. I made a screen recording, too. Also sometimes the crash reporting screen won't even appear, the app just silently closes.

As a workaround, I just downgraded to version 0.21.12 as it seems to work fine for me.

Could you test if #7704 solves the issue?
