Welcome to the forum! Please see how to ask for support so we can best help you.
You will need to switch into a tty (Ctrl+Alt+F3) and login with your username and password.
Then run:
sudo systemctl restart gdm
This will restart the GNOME Display Manager systemd service and should resolve your issue.
