gnome-shell freezes and restarts itself after login

[Daniel]

Dear developers,

After clean installation of Ubuntu 20.10, gnome-shell always freezes and then restarts itself when I try to open any application for the first time after a reboot. Also I can not find any crash log related to this occurrence.

This seems to be occurred after upgrading nvidia-driver to the latest available version (455) from "Additional drivers" menu. Reverting back to nvidia-driver 450 and the freezing issue is gone.

Thank you for taking the time to report this bug and helping to make Ubuntu better. It sounds like some part of the system has crashed. To help us find the cause of the crash please follow these steps:

1. Look in /var/crash for crash files and if found run:
    ubuntu-bug YOURFILE.crash
Then tell us the ID of the newly-created bug.

2. If step 1 failed then look at https://errors.ubuntu.com/user/ID where ID is the content of file /var/lib/whoopsie/whoopsie-id on the machine. Do you find any links to recent problems on that page? If so then please send the links to us.

3. If step 2 also failed then apply the workaround from bug 994921, reboot, reproduce the crash, and retry step 1.

Please take care to avoid attaching .crash files to bugs as we are unable to process them as file attachments. It would also be a security risk for yourself.
