Error Downloading game

I played the campaign for like 30 minutes earlier before going out to dinner. Came home, and the game wouldnt launch. kept bringing me to gaming services. So I uninstalled the game. Then it told me I wasn’t old enough??? My account says I’m 32. I’m a 32 year old male. I was EOD in the army. by god, I better be old enough to handle cartoon alien violence.
So deleted xbox app and all xbox related apps.
Rebooted pc. Reinstalled apps. Rebooted pc again for good measure. Now I get an error message when trying to reinstall the game for gamepass.
How do I play halo campaign without having to buy the full game when I’ve dumped a full games worth of money in the multiplayer and bought the game pass for the sole purpose to play the campaign the one time I’ll ever play it?
