friend cannot Launch the game, despite being able to run games with higher requirements, game simply will not launch.

battleye opens says launching game, marathon appears briefly in task manager and then closes, tried every fix online bar updating to windows 11, which friend is not willing to do (understandably) what's going on? game works fine for me and we regularly play games like arc raiders and others which all have much higher requirements? I also see people asking for help over a week ago with NO response by bungie, great game but things like this will kill it before it even gets running! for a game to look like deep rock galactic essentially it did not need to be this difficult to get running. due to failed attempts he has over 40 minutes logged in steam, despite the game not launchin past battleye even once!
