"Failed to open descriptor file"

I'm unable to launch the game today. Receiving this error each time:

It occurs after the "Easy Anti-Cheat" splash screen. I've already tried verifying the files via Steam. I didn't have this issues at all yesterday and haven't made any changes to any of the game files.

Issue seems to have resolved itself.
