It’s after recent update and switching back to earlier kernel doesn’t fix
I don’t have an Nvidea Graphics. Do I need to get the Nvidea drivers

Kernel 5.8 is EOL.

It happened when i booted after the update
I fresh installed manajro yesterday and don’t know how to revert and its not the kernel ig as I tried different kernels and they had the similar problem

Which kernel would you recommend? I’m quite new so I don’t know much.

Start with a LTS kernel. 5.4 is a good one. You can have multiple kernels installed and you can select them in Grub Boot Menu. Always install them via MHWD.

you should add theses kernels

sudo mhwd-kernel i linux419
sudo mhwd-kernel i linux54
sudo pacman -S linux419-headers linux54-headers 

change on /ect/grub/default

sudo nano /etc/grub/default
sudo update-grub
