Active User Signed out

I’m getting the Active User Signed out bug on both Xbox and PC versions of the game. Game was fine before today. Have searched for solutions online and while it seems like a persistent issue, I cant find a fix. Have tried signing out, hard reset on Xbox, clearing webcache on PC, nothings working. Wtf 343?

Can you describe specifically what this glitch is doing? I’ve gotten the popup too, but for good reason. Maybe I can help.
