Error code broccoli unfixable

Hello,

I have the https://help.marathonthegame.com/hc/en-us/articles/39002079777300-Error-Code-BROCCOLI since 1 month and a half now.
My windows is up to date Windows 11 24H2 build 26100.8737 
My graphic driver are up to date (running an AMD 26.6.4 with no update detected)
No other game seems to have any trouble. But I can't start Marathon, it crash after 5 seconds with the error code broccoli.

Can you help me with that ? I uninstalled my graphic drivers and the game, still the same problem.
