Hello everyone, Today I played Rust and logged off few hours later , After a few hours I tried to re-launch the game once again using steam and received that error code with those details:

Using Windows 11.

Answer 1

Possible it was also (2023-05 Cumulative Update for Windows 11 Version 22H2 for x64-based Systems (KB5026372)).

That's exactly what it was. Code integrity policies were updated, and EAC is either incompatible with core isolation features or deemed vulnerable to ROP exploits, so Windows prevents the service from launching. (Note: It's not just EAC ... several other anti-cheat services seem to be affected too.)

We're stuck with limited options on this one ...

• wait for Epic to roll out an update to EAC that Microsoft deems sufficiently secure,
• roll back that cumulative update (miss out on included features, rely on potentially outdated security definitions), or
• disable security features (namely hardware-enforced stack protection).

Never thrilled with rolling back updates or disabling security, but given the lack of public comment so far from Epic, I'm not super hopeful it'll be a short wait before we get the proper fix. I'm probably going to end up taking the third bullet over missing my weekend gaming.

Answer 2

They still haven't done a damn thing to fix this and its impossible to find any acknowledgement from EASY andti-cheat Microsoft or Battleye which also has conflicts with this new securty feature.

Answer 3

Same here with starting Elden Ring. Disabling the Kernel-mode Hardware-enforced Stack Protection did the trick. Validating the files didn't find anything missing. I had an update the other night too (right after the last time I played). Definitely something with the last Windows patch (2023-04 Update for Windows 11 Version 22H2 for x64-based Systems (KB4023057)). Possible it was also (2023-05 Cumulative Update for Windows 11 Version 22H2 for x64-based Systems (KB5026372)).

Answer 4

same for me

Answer 5

Hello Zoar,welcome to the Microsoft community, I'll be happy to help you today;

I understand that you are having problems with the Anti-Cheat of the Rust game on Steam;

Initially I recommend that you try to verify the integrity of the game files;

Open Steam and access the Library;
Right-click on the Rust game and go to Properties;
Click Local Files;
Click Verify integrity of files;

Wait for the process to finish and try to start the game again;

Hope this helps, see you soon!

I actually fixed it by disabling the Kernel-mode Hardware-enforced Stack Protection in the Core Isolation menu, However I'm not sure how safe it is when it's disabled.

Just to clarify I re-installed the entire game in attempt to fix that issue which has been resulting in a fail attempt.

Do you think that even after re-installing the issue can be fixed by your suggestion? because if so I will enable it and try it.
