Gnome keeps showing welcome window

I have a super weird problem
I installed Gnome edition and used it for quite some time
Then I closed laptop’s cap , placed it in another place ,opened and…dark screen and system didnt react on my taps on keyboard
I thought that nothing bad happened
Turned it off ,then on and…welcome windows
That very window where you tipe your data (username ,password keyboard layout)
And when I restart the system I see it again even if I fill everything it wants
(If something I have Timeshift backups but dont know how to use them)
Apreciate all your help))
