Yesterday, I put my laptop into sleep mode , but after a while I found it still on, and very hot and the fan was at full speed while screen was off. Tried everything to turn the screen on, but at the end I forced power off with long pressing on the power button.

After that, whenever I turn it on, the grub menu apears normally, then it displays this glitched text!

I tried blindly typing my user name , Enter then my password , but it didn't change ... I couldn't tell what's going on.

I'm using AMD APU, with the open source driver which i haven't faced any issue with while playing videos and such.

I used endeavourOS live CD to arch-chroot into my disk and did a full upgrade with packman -Syyy then pacman -Syu

I installed the lts kernel alongaide the existing version 15.x, tried booting with lts version but no success.

I also installed and enabled lightdm instead of sddm.

I tried putting 3 at the end of the line starting with Linux in grub config menu the pressed F10 to boot in tty mode, but the problem remains!

What should I do to display that text normally so I troubleshoot the original problem that occured with sleep mode ?

Also sorry if that was a common problem with AMD or whatnot, but I couldn't find the correct words to describe the issue thus making my own research.
