inability to enter certain craters in passwords when logging in.

After starting Ubuntu, I wanted to connect to my account (let's say my password is: Oppö1568). The normal behavior would be to enter my password and log in.

But it's impossible to enter the character ö (this also applies to craters with ^: ê, â, ô, ...) instead of my password I have : Oppo1568 . (Please note that this is not a keyboard configuration problem. The problem of no longer being able to type the characters: ê, â, ô, ö, ë , ä, ... arrived with the Ubuntu update 24.04.
