Cannot resolve broken state

I don't know how this problem came about. I had the systemd timer running for a few days, and it looks like I've three snapshots of the home. subvolume and four of the ROOT. subvolume on the remote. I was trying to confirm new commands by running btrbk, but it gives me the error;

```

If I do `sudo btrbk clean`, I get;

I tried logging into the remote host to do `sudo btrfs property set -ts ROOT.20220427T0000 ro false`, I just get `ERROR: Could not set subvolume flags: Read-only file system`.

So I'm a bit confued and lost! Any advice would be apprecieated, thanks!
