So I received the invite to join the Halo Infinite - Insider and redeemed the code on Steam then downloaded the insider. Everything launches fine I get to the main menu and the problem occurs when it asks me to login to my Xbox account. At first I put in my email and password and after that a blue box comes up that just says -101 in the left corner. Now every time I launch the game it doesn’t even give me the chance to login with my email and password I just click login and the -101 blue box pops up I restarted my PC, closed Steam, closed Xbox related apps, and shut everything down with task manager nothing works. Please help thanks.
I have the exact same problem. I tried the same methods even reinstalling on another drive.
