Game Won't Launch

Whenever I try launching the game on my PC the windows will pop up for a split second then close itself, i’ve been having this problem since before the Colony update came out. Please help.

Try reinstalling the game? I had a similar problem, and that fixed it for me.

I don’t know how to uninstall it from the windows store, do I use the Halo launcher app?

For me a Chrome tab popped up saying the game couldn’t connect to a server.
I had to log out and in again on the Windows Store to get it working.
