KF *cant open KF, critical error, please help!!!*

I have been playing KF1 for a few weeks now, and I'm enjoying the game very much. A few days ago, I have been getting a critical error on game startup. I'd go through the 2 developer/publisher screens, and before I run into the solo/multiplayer mode select screen, a critical error would occur. I've done the steam client registry blob rename, restarted steam, reinstalled KF, deleted KF system folder, and verified game cache, but now the game won't open. It no longer enters the black startup screen before the 2 developer/publisher screens. When I start KF, it simply shows the "killing floor co-op survival horror" mini screen that pops up in the middle, then it goes away and nothing happens. I've included the error log that I was getting before trying solutions and tampering with files, and can upload anything else if needed. Thank you in advance.
