I’m just reporting a workaround to an EAC bug.
I could not play Rust since August 2015 to now, due to a weird bug that the Rust launcher fails to load with EAC enabled (and gives no crash report)
I had an EAC error “Rust Launcher Error: LauncherFailure - Game startup failed. Error Code: 22” when I try to launch Rust through Steam.
I’ve tried reinstalling Rust,
disabling anti-virus software,
switching off audio devices,
launching Rust as admin,
using -force-d3d11 in launch parameters,
and changing/removing registry values of EAC.
Nothing above works.
But I reinstalled Rust in another Steam library, it gets to work.
I don’t know exactly why it works now but I think “symbolic link of directory” is the key.
My actual “Program Files” directory lies on D drive(HDD) and I have a symbolic link of the program files directory on C drive(SSD).
I moved the steam library from D drive to another HDD (that is M drive now) so that Rust can startup with EAC.
I hope this info helps to some people struggling with EAC problems.
