EDIT: I kinda solved it by installing Wayland (with Nvidia card, Ouch!) to replace Xorg. Not sure if this is gonna last though. Perhaps Manjaro is the one I'm gonna throw out FIRST if anything happens from now on.
What should be the first line of defense? Timeshift?
This happened after I installed AUR package masterpdfeditor and 2 applications from github (some hashing algorithm programs, I think they were "Dilithium" and "Latice-based-cryptography-main", one of them was provided by NIST.)
If using GUI: I login, black screen for few seconds, then back at login screen.
If going to ctrl+alt+f2, login successful, then startx, see picture provided (higher quality).
I tried adding a new user, but result is the same.
I have a live usb to do the Timeshift. (I can also chroot if necessary... But I'm not extremely professional)

It also contains the logs people mentioned I should check. The
Xorg.0*files are from the day of the crash, and 2 days later, when I booted again, the other files were created:Xorg.1*I was under the impression that
startxwould just start the GUI regardless what display manager I use (lightdm? not sure), or display server (xorg, x11 in my case) I have installed.EDIT: it took me wayyy too long to copy these files. Apparently
ls -lhdoes not show hidden files ... I thought my whole laptop went nuts.You're god damn right
