Hmm 
just a guess but could this be a kernel issue? Have you tried the LTS kernel? If not here is how you can try it out,
Use
garuda-chroot -a
To chroot into the system, in case this fails (happens if you have ventoy on your USB stick) you can look at this post to manually chroot into your system → How to chroot Garuda Linux The post goes on to explain how to reinstall grub you can try that as well but here is what you need to do to install linux-lts.
Once inside the chroot env.,
pacman -S linux-lts linux-lts-headers
then exit the chroot env, reboot and from grub’s advanced menu select linux-lts. See if having a different kernel makes any difference?
