Game refuses to fully launch after latest update.

As stated above, my game has refused to launch after the latest patch. I have done everything on my own end to resolve this: i.e. fresh install, deleting specific folders, updating drivers, fresh install on a different drive, etc. I have the game purchased through Steam and before this latest update, I was able to play it just fine. Now, it only opens a black window for a second or two before closing. It doesn't even make an attempt to load. I have over 100+ hours in this game and I am now entirely unable to play it and cannot even request a refund. (Not that I'd like to. I'd like to be able to finish the game. :/ )

I have seen others have this problem, but there doesn't seem to be a fix. I hope that perhaps a fix can be released in an update soon to sort this issue out. I'm not sure what else I can do. I have attached a screen recording to show what happens on my end.
