I wanted to try out Timeshift instead of Snapper.
Okay, I like snapper better. 
So I reinstalled the snapper packages.
Problem: my previous snapshots don't appear anymore in Snapper tools. But I think they are still there, and eating up lots of disk space. How to delete them manually?
See screenshot.
I’m not familiar with Timeshift and Snapper, but first, you need to show all your subvolumes.
Hopefully the standard command would work:
sudo btrfs subvol list /
Plz post output from the terminal (no picture of the terminal plz).
sudo btrfs subvol list / 20:14:33

This is the one from Timeshift, I don’t know the @_backup, maybe those are Snapper’s?
What if you try
sudo btrfs subvol delete timeshift-btrfs/snapshots/2022-11-22_19-24-27/@
Hum, I think it won’t work cuz it’s the same Level 5 as your root. I can’t recall, let’s see what you get.
sudo btrfs subvol delete timeshift-btrfs/snapshots/2022-11-22_19-24-27/@

ERROR: Could not statfs: No such file or directory

Maybe I need to mount the root somewhere, to reveal the true path. If you think that might work, please guide me how to mount it.

Ok so that's it you have to mount your disk partition somewhere, like in /mnt, so you can access all subvolumes from a higher level. Been a while I haven't played with that.
Once you mount your disk partition into say /mnt, you can issue:
sudo btrfs subvol delete /mnt/timeshift-btrfs/snapshots/2022-11-22_19-24-27/@
If you don’t know how to mount the partition like that, plz provide garuda-inxi output.

Is deleting the subvolumes from btrfs assistant not an option?

I ticked the little box at the bottom, "Include Timeshift and Snapper Snapshots", and that did it. After deleting the backups, my disk space was recovered.

If i were you, I'd also run garuda-update remote reset-snapper real quick, since you may or may not have deleted a subvolume or 2 necessary for normal snapper operation.
