please fixing this bug.

I assume "that" is 3 lines icon and then drop menu?

Tested in waydroid and Xiaomi Redmi 8 (LineageOS 23). Can't reproduce ¯\_(ツ)_/¯.

You can reproduce it just after opening the app without any additional conditions?

[jehad-husein]

@dustdfg Yes, I can reproduce it immediately after opening the app.
Steps:
Open NewPipe (fresh launch).
Tap on the service switcher (the “YouTube” text in the top bar, not the 3-lines menu).
Try to switch to SoundCloud (or any other service).
Result: the app crashes instantly with a UI error.
No additional conditions needed (no video opened, no scrolling, no backgrounding).

@jehad-husein can you make a screenshot or explain differently? Because as far as I know there is no button for switching service on topbar. There is dropdown menu in left drawer with service switch but it is hidden in 3-lines menu so I can't understand what are you talking about. Can it be that we talk about the same thing but with different words?

[absurdlylongusername]

@dustdfg I think this is a case of misunderstanding due to ESL. I have been able to reproduce this just now. It is indeed in the three lines menu. I tapped the service switcher dropdown while it was already set to YouTube, and got the same error.

However, I'm using my own apk that I last merged with dev on 15 Dec 2025. I check if I can reproduce this on current dev branch.

I can replicate this on Nightly 1094, but I can't seem to replicate it in emulator on dev latest. I tried both in debug and release mode but it doesn't work. Idk why.

[jehad-husein]

@dustdfg

Sorry I couldn't explain it well. I gave you a screenshot, you can see it.

[absurdlylongusername]

Bug is not present on NewPipe 28.0.

I have done git bisect and identified #12776 as the PR that introduced this regression.

Possible offending commits are:
4a8592c
8f91f21
0a0f28e

0a0f28e Probably only plausible one as this the only that changes real dependencies.

[absurdlylongusername]

Problem is we changed material from 1.11.0 to 1.13.0. Switching it back to 1.11.0 does not have the bug.

Apparently it's something to do with accessibility. I don't have a good idea yet. I wasn't able to find much on google, but I consulted with Le Clanker and it dug up this stackoverflow post with no answers (classic).

Easy fix is to just go back to 1.11.0 or 1.12.0 if that also works. Ideally I'd wanna know why the heck this is happening in the first place though.

UPDATE: More investigation, I'm only able to reproduce this while I have Vigilante enabled in accessibility services. If I disable it, the error disappears. I was not able to reproduce this on emulator because the emulator had no accessibility services, but once I installed vigilante the problem appeared.

I also installed TalkBack, but that didn't trigger the bug. However, I don't think the bug is unique to Vigilante, but rather a change made in Google's Material Components is causing this to occur when Vigilante is enabled, and probably the same with some other accessibility services.

@jehad-husein What accessibility services do you have enabled on your device? If you go to Accessibility in Settings, it should say if you have any installed/downloaded services.

[jehad-husein]

@absurdlylongusername
Thanks for looking into this.

On my device, the crash occurs while accessibility services are enabled.

Currently enabled accessibility services on my phone:

• BlockerHero (ON)
• Smart Launcher Gestures (ON)

Other accessibility options like TalkBack, Select to Speak, Magnification are OFF.

[jehad-husein]

@absurdlylongusername

Sorry if this feels repetitive, but I wanted to share a confirmed finding.

I tested this by turning off apps that have accessibility permissions one by one.
I noticed that when I disable accessibility permission for an app called BlockerHero, NewPipe works fine and does not crash.

However, as soon as I enable BlockerHero again and grant it accessibility permission, NewPipe starts crashing again when switching (e.g. to SoundCloud).

So it seems the crash is directly related to BlockerHero being enabled as an accessibility service.
