Still missing files

For some reason after reinstalling the game 4 times already, i cant play it at all because the message “Missing files” keeps coming up

I have tried everything:
Launch it as an Admin, restarting my PC, pressing “Check updates” in the microsoft store over and over.

I have TMCC and Halo Reach installed but for some reason i keep missing content i dont know how or which one and the Halo Support Page does not address any of the issues at all

Please see the pinned thread regarding Halo Support and how to submit tickets for issues you may be experiencing.
