Can't play rust after the update!

Hello, after the update i can’t play rust at all. I can launch it but while it’s loading it crashes at “Running self check”
I’ve tried the following
Re-installing rust
Re-Installing Steam
Restarting computer

I have the same problem, and when I could get in game and attempt to join it says EAC disconnected.

The error I was having is that I was running it from the taskbar.
