Playing on PC, bought and launched from ubisoft connect, i9-9900K, RTX3090, 64GB RAM.

Game crashes to desktop no matter what I do. I tried launching as administrator, I tried shutting everything in the background down, I tried turning off every overlay, I tried running at stock speeds for everything, I tried running on lowest settings, and the result is always the same: after 1-5 minutes the game closes out to desktop, no error, no crash report, nothing.

All drivers up to date, clean install of windows, verifying files gives no prompts of issue.
