Additional information

i have set the animation scale for all animations to 0 on my device.
within less than 30 seconds after this error occurred i got an anr for system ui.

i am uncertain if i should check
I am able to reproduce the bug with the latest version.
as i did have it occur on the latest version but it is currently only happened once and i have not been able to reproduce it again after.
and
I am not able to reproduce the bug with the latest version of vanilla NewPipe.
as i can't get this to happen on vanilla NewPipe but i don't know if that means that it doesn't exist on vanilla NewPipe.
though it appears that i have to check them both to create the issue so that's what i did.

also i currently can't read the faq as https://newpipe.net/FAQ/ is down atm.
