GDM doesn't start when booting a snapshot

I understand snapshots should boot into Gnome from this thread, but it still isn't working for me. Instead I get the errrors:

[FAILED] Failed to start Annonymizing overlay network for TCP.
[FAILED] Failed to start Annonymizing overlay network for TCP.
[FAILED] Failed to start Annonymizing overlay network for TCP.
[FAILED] Failed to start Annonymizing overlay network for TCP.
[FAILED] Failed to start Refresh Pacman mirrorlist with Reflector.

And that is all. I can CTRL+ALT+F2 to go into TTY2 or I can CTRL+ALT+DEL to restart. SSH is also working. It seems GDM doesn't start for some reason.

How can I troubleshoot this issue? I would like the snapshot to start Gnome if possible.

It looks like you are still trying to boot into a bad snapshot. Try booting into your working system, then create a new snapshot and test if you can restore that.

Those error messages look like they are related to a network problem, not anything related to booting your system. The first one, is that Tor? You should be able to boot your system even if Tor is broken.

How do I know if it is a good snapshot? I booted the snapshot that was created just before rebooting this morning. The snapshot was created today when I ran garuda-update.

Have you tried booting into the pre-update snapshot? In case something from the update is breaking your setup.

Yes. That's what what this thread is about. I tried to boot a snapshot from a working configuration but GDM isn't starting. Can I get the errors from GDM? Perhaps I should check journalctl after starting the snapshot.

I'm still having the same issue. Here is my GDM log when starting a snapshot.
