Since i updated Kde Neon to 5.16.0 cannot login.
I see the new login screen and a virtual keyboard prompt up. I write my password but there is no way to go through. No pressing enter, no doing it through the virtual keyboard, there is not any button to do it. Nothing.
I only can write the pass but not enter to the system.
Please help.

When the login screen appears, enter the terminal ctrl_F2,F3.... and try logging in. You can try recovery mode and login as root and change passwords
