This post explains everything that's I've been going through, but the steam forums are saturated so I've came here.

Tl;dr

  1. I was playing the game yesterday
  2. Seen a feedback button so I clicked it
  3. Game closed, malwarebytes blocks an executable
  4. Restored everything, put exclutions, repaired EAC, verified game cache files
  5. Getting an "Access is denied" everytime the EAC loads.
