i have been having similar problems in the past with my RTX4080 card. i got two solutions you can try
RESTORE a SNAPSHOT, boot into LTS kernel if you got it. and then apply these solutions to see if that helps
Have you tried using this solution? It has worked for others with those problematic Nvidia cards
sudo pacman -R garuda-nvidia-config garuda-nvidia-prime-config && sudo pacman -S nvidia-open-dkms
The follow solution the Garuda team does not recommend, but it has saved my installation a few times already, without any other problematic issues so far.
This solution means downloading nvidia-all drivers from git, which will give you options to choose between different versions, and so try different versions than the latest one. The trick, when using this solution, is to watch your terminal while compiling the dkms modules, and if no errors are thrown up, that particular version ought to be fit for usage. You can also choose between open source or proprietary drivers.
git clone https://github.com/Frogging-Family/nvidia-all.git
cd nvidia-all
makepkg -si
sudo dracut-rebuild
sudo update-grub
