Halo 2 Insider testing not launching?

Hey all, I was invited to test with the Microsoft Store invite and, after following all steps carefully, I’m stuck at a screen that just shows the name of the game and nothing else. It has no option to maximize, minimize, only close. There are no additional buttons on the screen.

Any tips or am I missing something? Much appreciated ty

Edit: I fixed the issue, I just had to sign in to the Microsoft Store with the account I registered with Halo
