Random boot to menu

I started playing war zone yesterday and keep getting booted to the screen where’s its says quit activity, carnage report and Spartan hub and I can’t rejoin the match because it stays on that screen into I quit halo 5 guardians so annoying when I just playing war zone and booted to this screen where I lose my req boost and have to start another match and only to hope it won’t boot me to that screen any ideas on how to fix this?
