Download not proceeding after 18% in Halo MCC in Xbox Game Pass and then downloading stuck...

Same, games recently downloaded on Ultimate Game Pass aren't working for me (Halo 5, Halo MCC, Hue, PES2019) with that same error code, but older downloaded games are working.

It took me 18 hours to download and install Halo The MCC collection, had it been on PS4 I'd still be downloading it. Xbox One is not as fast as I would like, but it's still a lot faster and a huge improvement compared to my PS4.

The download itself is extremely slow. It took me 3 hours to download and I have 50mbps down. Plus its also happening to halo MCC now. If your download gets stuck guys just pause it. Then unpause it. No need to restart the whole download

Hey I was experiencing the same thing. Try holding down the power button on the xbox until it turns off. Then unplug it from the wall (must be plugged into wall otherwise it would cause more issues) and leave it for 5 minutes until the light on the brick
turns off. Once it's off plug it back in and resume the download. Hope this helps!

I believe you'll need to download the MCC. After launching it, you can choose which Halo Games you want downloaded in the MCC
