Spartan Strike (PC) randomly shuts down

I was just playing Mission D 3 or 4 and my game shut off completely on its own. it seems to do that a lot ever since that one update patch came through. never get to play more than two levels/missions before it does this. Why is it even doing that? i am signed in as SkyHawk40, my gamertag. this is on PC, and has happened ever since the update/patch happened years ago. i love the game, hate the bugs.

Are you still experiencing this issue?

I played on my W10 laptop during the spring/summer 2018 and didn’t see this problem.

I just played mission E4 without any issue.
