I was messing around with the dev console using unren and got some error message so I closed the game and when I went to reopen it the splash popped up and when it got to like 95% it would just close. So I deleted it and redownloaded a fresh copy with no unren installed and the same thing happened, I then downloaded it to a separate external hard drive and it happened again. I have no clue what I did or what to do to fix it.
