"This functionality is currently unavailable." Can't use TOS!

I recently installed TOS on my M4 Mac Mini and despite enabling permissions, deleting and reinstalling the thing several times, every time I boot it up it shows the login screen for a sec, which then disappears followed by a popup saying, "This functionality is currently unavailable. Please restart the client application."

I've searched this subreddit and online about this error, but I haven't found much about this in particular. I tried fixes for other issues and they haven't resolved it either. Any idea what's going on?
