The game told me to report this

My controller died so I said screw it and turned off my Xbox One. When I rebooted my xbox one and started Halo MCC I got an entire black screen but with red print in the top left corner saying "File upload to server failed. Please visit the Halo: The Master Chief Collection site and report this. [safe to reboot]

I do have an image of it but I do not know how to upload to this website.

This same thing just happened to me during a Custom Game with some friends. Completely random, and in-game. I have a clip of it here:

It appears to say something along the lines of:
“Uploading files to server, please wait. Something bad happened. Visit the Halo: The Master Chief Collection site for more information (Please don’t reboot)”

And then the text changes to what you said above:
“File upload to server failed. Please visit the Halo: The Master Chief Collection site and report this. [safe to reboot]”

Same black screen crash and error message while playing ranked h2 anniversary multiplayer. Happened in the middle of game. Had to reboot console.

wow more and more problems are popping up
