Welcome to the forum!

Kernel 5.12 has already no longer been supported for quite some time. Please update your system ─ your inxi output suggests that you haven’t, because you’re still on Plasma 5.22.5 while Manjaro Stable is now on 5.23.3 ─ and upgrade to kernel 5.14, or install one of the LTS kernels.


sudo pacman-mirrors -f && sudo pacman -Syyu && sudo mhwd-kernel -i linux514

This will take quite some time, so let it finish and do not interrupt the process, because it would leave your system unbootable.

Linux 5.14 is also EOL.
