MCC on PC Xbox Game Pass - Wont Open?!

hey, so I just downloaded MCC to play Reach via the xbox game pass beta on my PC. It finished downloading, but when I go to click play nothing happens. The Game Pass UI closes and then nothing happens, no game, just my desktop. Restarted my PC and same thing, and I know it’s not my specs because I’m able to play CoD MW on high settings no problem. Any fix for this?

Edit 1: I’ll add further, Windows and drivers are all up to date so no issues there. doing a reinstall of MCC now, to see if that will help

Edit 2: redownloaded, still didnt work through the xbox game pass. went a round about way through the xbox store library, installed reach again through there then launched the game through that as well and it seems to be working! got to the main menu, will update if anything else happens

I had to go to the start menu to start the game, from windows start menu and typing Halo.

Just a note, it might freeze after you selet your id or whatever. I had to wait for 2 mins or so and it gets into the main lobby.
