This suggests your kernel is missing or has disabled the graphics
driver. Please ensure you are not using the 'nomodeset' kernel
parameter.

I am running OOTB kernel.

This may also be related to the problem you describe so please 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.

If I look at the list, two reports seem related (in 2022):
* 2022-05-01 09:05      2022-05-01 07:05 UTC    Crash   
/usr/libexec/gnome-session-binary 
(https://errors.ubuntu.com/oops/dccbb020-c91f-11ec-99b8-fa163e55efd0)
* 2022-02-17 07:02      2022-02-17 06:02 UTC    Crash   gnome-settings-daemon 
(https://errors.ubuntu.com/oops/567662b6-8fbc-11ec-88ab-fa163e6cac46)

I can not see any details for both or them, because I get the message:
"Sorry, you are not a member of a group that is allowed to see the data
from error reports. Please fill out this form to request access.".
