Stall when pressing login button

Dear all,

I have been using Manjaro without any major problems for the past year or more. However I’m now facing one that I can’t seem to be able to resolve.

Once I boot and arrive to the login page, I can enter my password but once I press the login button everything freezes except for the mouse cursor which I’m allowed to move.
I tried rebooting several times but nothing changes. I looked up on the various forums for a long time but (maybe due to my incompetence) I’m not able to resolve the issue.
I also tried creating a new user through the tty but I get the same error.
Often was suggested to login from the tty and run the command ‘sudo startx’. The following is what I get:

“X…Org X Server 1.20.8

Any help would be really really appreciated.

No. You never use sudo startx with your username … is messing the home permissions. Fix that with:
sudo chown -R $USER:$USER $HOME

If you use the .xinitrc in your home directory then change from:

You did not updated the system in long time. Stable branch is already at 4.19.154 kernel version …
