R6S Won't Launch At All?

Hey everyone, so I haven't played Siege in a number of months, and just re-downloaded it to start playing with some new friends. The only problem is that when I hit "Play" on Steam or UPlay... nothing happens. It flicks "running" and then "syncing" on Steam for a few frames and then disappears altogether. Task manager shows nothing running. All of my Nvidia drivers are up to date. And the game is a fresh install. I've tried "turning it off and on again" and a few other simple tricks like running in compatibility modes and as admin, etc.

​

This is Windows 10.

​

Anyone else have this issue recently or know of a fix?
