Hi there, welcome to the forum.
I think you’ll have to adjust the UUID’s of your partitions in the /etc/fstab file (they might have changed in your resizing) and I’d also reinstall the GRUB.
To do that, you’ll have to chroot into your installed system from the Garuda live USB using this procedure:
PS: you’ll have also to remove the swap line from fstab and swapoff, if not yet done before removing the swap partition.
