Windows 10: Why can't I download Halo: MCC on PC?

I've tried everything on the internet up to and including resetting my windows install drive to factory but no matter what I do I can't download the Halo: MCC on my PC. I can download most other games, but nothing I do will allow me to download it. The worst part is that I had it on my computer, then I went to play it about 2 weeks ago and it gave me an error, said the game wasn't installed and has been broken ever since...

EDIT: This is through the Xbox Game Pass Ultimate

Halo MCC PC

Hi,

I know Halo MCC (specifically Reach), will be released on December 3rd, 2019. Is there a specific time this will be released?

 

Halo : MCC for PC installation - Cannot Find Device

Hello! So i got the pre-order of MCC and now, release date! Went to the Purchase history on the Microsoft Store to download. NO DEVICE FOUND. (meaning my computer) hmm... So i made sure i was currently Signed In thru my Microsoft Account. CHECK! I signed
out, and resigned in. NO fix. I went thru my OWNED list of Apps, where i also see Halo : MCC with a ! where INSTALL should be. Hover over and it says that I cannot install that game on my current Device (Windows 10) a couple days ago, i made sure windows and
PC were up to date, which they still are.

So what am i doing wrong to install the game onto my PC? It was made for the PC.

 

Halo MCC for PC

I recently bought the MCC on Pc, and it came with Reach at no additional cost. Will the same be true of the other games as they are added to the collection? Will they be automatically added to my library as free dlc, or will they have to purchased individually?
In other words: have I screwed myself by getting excited and buying MCC early?
