Forza Horizon 4 won't launch

My FH 4 doesn’t start
i already tried:
restarting Pc
updating Windows/drivers
making a exeption in my Anti-Virus programm
deinstalling MSI afterburner
installing a small app from MS Store

in Event viewer it says DCOM error 10010

(sry for bad english)

You’re out of luck, it’s a Microsoft Store problem. There’s going to be a patch for FH4 coming tomorrow, so try that, but I can’t promise anything since I can’t start my game either ever since I installed it before Christmas. I get DCOM Error 10001 “Unable to start a DCOM server” and I’ve tried everything except reinstalling Windows.
