I found another workaround and it's easier than EVER and it's done via
mkinitcpio😁


First, what's mkinitcpio(https://wiki.archlinux.org/index.php/Mkinitcpio)?



The initial ramdisk is in essence a very small environment (early userspace)
which loads various kernel modules and sets up necessary things before handing
over control to init. This makes it possible to have, for example, encrypted
root file systems and root file systems on a software RAID array. mkinitcpio
allows for easy extension with custom hooks, has autodetection at runtime, and
many other features.

So go ahead and edit with `sudo nano /etc/mkinitcpio.conf`


Then add the "amdgpu" in the modules section like this:


`MODULES=(amdgpu)`


After that, simply run `sudo mkinitcpio -P` so that it regenerates mkinitcpio
for all kernels


This solved my issue, I hope it works for others too :)_
