PBP Went Blank After Login

[Tharadash]

Hi,
I really really enjoy PBP Manjaro for many months.
Until recently, after I keyed my login password, the login screen continued as usual for a few seconds and then the screen gone blank. I noticed the green LED and noted the laptop is still running, but with a blank screen.
I’m no Linux expert. Please advise what shall I do.
Thanks.

 I'm facing a similar issue with Fedora 33 on kernel 5.7 by armdevelopers.

However, my install switches back to the login screen after about 2 minutes, after which login works fine without crashing a second time.

What happens, when you try to switch TTY?
Is there any output on your screen when pressing the arrow keys?
