A couple of friends in my squad couldnt even load Halo Infinite Up since de Season 3 Update on PC! We tried updating drivers, validating files on steam, opening it on Xbox App, and nothing works! Please if somebody knows a Fix, or if you’re experiencing the same problem, let us know so 343 can do something about it
My bros and I want to play this new season!!
Same here. After the update, It crashes without error messages while loading the 343 industruies logo at the beginning. I made a ticket already but nothing happened.
Same here. Happened as soon as i pressed space bar.
Same here. It launches and gets to loading and crashes when it’s about 85% done. Tried everything and nothing works, I can’t even play the campaign 
Check your firewall settings and make sure Halo is added to the allow list.
Same here - the app crashes within a few seconds of pressing play on steam. I have also opened a ticket.
same here the game crashes almost instantly after pressing play on steam
This really sounds like a firewall issue to me. This “update” was not an update, it was totally a new game download replacing the existing one. Go to your firewall and make sure Halo Infinite is added to the allow list. If not, allow it.
