Can't launch Dirt 4 - OG Xbox One

Just got the game, courtesy of Game Pass trial. Installed it - all 33 gigs of it. Did not launch it until it completely download.

It says "an error occurred during the system update" when I try to launch it. What's this then? I have the latest system update and every other game is launching/running just fine. I've tried restarting my console and did a hard reset too.

So now what? Re-download the game again?
