Settings problem

I have touched the settings and I can’t go back. Since I changed the settings, every minute I get a message in the middle of the screen that prevents me from reviewing. I can remove this message but it comes back the next minute. Do you know how to remove it permanently?

The message probably comes from an add-on. Disabling it and restarting Anki should fix the issue. You’ll need to disable/restart one-by-one to find the culprit.

It’s the Timebox time limit preference setting: Preferences - Anki Manual

Ok thank you very much, it works !
