Syncthing-gtk "can't invoke the daemon"

When I open up Syncthing GTK (from chaotic-aur) I get an error that it can’t invoke the daemon. It seems to think that file doesn’t exist, but I have checked the folder and it’s there. This same app was working fine on a previous installation. Any ideas how to fix it?

I’ve tried rebooting reinstalling both syncthing and syncthing-gtk. I checked the github and found no issues related to this error.

I did get the Flatpak working, but it was stuck in light mode, so that’s not my favorite plan.

Failed units:

Check whether ~/.local/state/syncthing/syncthing.lock exists (w/o this file, syncthing does not start, which in turn triggers the described error in syncthing-gtk).
If not, then create the folder syncthing under ~/.local/state/, and in this folder create an empty file with the file name syncthing.lock.

After that syncthing and syncthing-gtk should work w/o any issues.

Thanks! I don’t have access to that computer today, but I’ll give that a try.
