Can't get rid of the "This screen doesn't support that action." message.

[VladN]

This message randomly showed up on my screen after unlocking my tablet, and I can't get rid of it. Tapping it doesn't make it go away. Closing all apps doesn't make it go away. Pressing buttons on the pen or clicking it with the pen doesn't make it go away.

Probably restarting the tablet OS will fix it, but I want to know what this message means and why did it show up. And the fact that I can't get rid of it is clearly a bug that Samsung should fix.

Happening on a S8+ 5G OneUI 6.1 Android 14.

Later edit: a reboot made it go away. Still, quite annoying.

@VladN I would suspect that a 3rd party app is causing that pop up.

I doubt that, since closing all apps didn't make it go away. And there is another similar error on this forum:

@VladN Closing all apps doesn't shut down background processes, etc. If you boot into safe mode, all 3rd party apps are disabled while in safe mode. Of course, often it isn't useful to stay in safe mode for long periods of time.
