Linux 6.5 boot freezes during startup !

My Linux RHEL freezes at initializing (loading). The usual bar that appears at the bottom of the screen during loading shows up and increases until about almost ready to load the desktop, but instead , the bar freezes and stay there.

The last think I was doing was playing with adding new repositories and downloading files. I don't know much else. I Don't know anyting about troubleshooting.

Any help here?
