Gitlab does not work after installing docker

Hello,
I am using Debian 12.5

So my gitlab was working normally, except i was having some issues with using the gitlab CI/CD via shell, so i decided to install docker. It worked fine except i needed to restart after adding docker usergroup to my user. After restart, my gitlab keeps " Waiting for GitLab to boot" forever, and i see error 502.

I checked this: Gitlab not working after reboot
but it doesn’t really answer anything. Any help would be appreciated.
