From the terminal you should shift+ctrl+C to Copy. Then past here.
Anyway
sudo mkdir -p /mnt/broken
sudo mount /dev/nvme0n1p2 /mnt/broken
sudo garuda-chroot /mnt/broken/@

mount /dev/nvme0n1p1 /boot/efi
grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=garuda --recheck
update-grub
