Xbox Account Required, but already logged in

[Yooj]

Hello, I am running Grounded through Steam, playing multiplayer with another person hosting. I never had any issues connecting until tonight. Now whenever I open the game I get the below error message, saying that I have to be signed into my Xbox Network account in order to play multiplayer. Opening the Xbox Console Companion I am 100% signed in. 

Things I have tried: 

Restarting computer

Signing in and out of the Console Companion

Signing into an alternate account on the Console Companion

Launching the game from the Console Companion.

Launching the game straight from the application and not from Steam. 

Repairing my copy of Grounded

Whitelisting the folder, as in https://www.reddit.com/r/GroundedGame/comments/uxyrtc/cant_sign_in_to_xbox_live_fix_steam/

Deleting the windows credential, forcing the game to make a new one

Downloading and installing the new Xbox app an trying with myself signed in from there instead

Thanks in advance for any help.
