Edit: Do what filo says first.
If you believe it’s a kernel issue why not try switching? From the live USB (if you haven’t reverted the snapshot) chroot into the system using garuda-chroot -a or if this fails (can happen if using ventoy) you can manually do the same following this → How to chroot Garuda Linux this guide goes on to reinstall grub which you don’t need to do, just enter chroot.
Once inside chroot try to install LTS kernel,
sudo pacman -S linux-lts linux-lts-headers
Then reboot and from grub advanced options for garuda linux select boot with linux-lts and see if this works?
If this doesn’t, you can chroot again in your system (remember you can follow all this after reverting a snapshot as well) and then provide us with the update logs.
cat /var/log/garuda/garuda-update | nc termbin.com 9999
This will upload the logs to termbin.com and provide you with a link please share that link with us. Termbin will temporarily host your logs so that you can share them with anyone using the link.
