There's a lot more than one way to do this. As one possible example:

When I mount my root filesystem using:
$ cryptsetup luksOpen /dev/sda2 /dm_crypt
$ Enter Passphrase:
$ mount -t btrfs /dev/mapper/dm_crypt /mnt
$ ls
I get:
bin boot dev etc home lib lib64 lost+found media mnt opt proc root run sbin srv sys tmp usr var
There is no listing of subcolumes. Where exactly are you getting that from ?
# mv root rootold
# btrfs sub snap root.20201126 root
# reboot
I can't do this because I have no idea what to mv on.
I think all my info is in the toplevel volume.
which is why I say the installer is not correctly setup for snapshots in BTRFS.
