Btrfs system wont boot from the default subvolume?

sudo snapper rollback

You shouldn’t do it for Manjaro and Arch based distros, but it only works for OpenSuse.

If you want to revert back to the default subvolume ID 5 (FS_TREE), here is a solution:

$ sudo btrfs subvolume get-default @
ID 352 gen 3478 top level 262 path @/.snapshots/79/snapshot
$ sudo mount -t btrfs -o subvol=/ /dev/disk/by-uuid/c863c9b5-d87a-4196-bdfb-5002d20e4ce0  /mnt
$ sudo btrfs subvolume set-default /mnt/
$ sudo btrfs subvolume get-default /
ID 5 (FS_TREE) 

Then fix your fstab:
