Hi @FlyingMetal, welcome to the community.
Try switching to a different kernel and see if the problem goes away. There are many different kernels you can try; the LTS kernel is a good place to start.
First bring the system fully up to date:
garuda-update
Install the kernel and headers:
sudo pacman -S linux-lts linux-lts-headers
Then reboot, and on the Grub menu (the menu before you get to the login screen) choose advanced boot options and find the entry for your new kernel.
