Anybody having the same issue I’m having? This just started to happen on me, launching the the Halo MCC and I get this message " Please try again. For some reason Halo:TMCC took too long to start. (0x8027025)"
I can certainly say I haven’t encountered this message, but I’m sorry that the game won’t even let you play it at all now.
Its a common xbox one issue. Do a hard rest and it will be fixed
Having the exact same problema, unplug console 10 sec and try it again
