um what. @DHowett ‼️ I've never seen anything like this.

Is it cause we have a dependency on 2.7.3, but that's not rolled out yet? I literally have no idea.

UH WHAT

MUX isn't linked by ordinal (or at all actually... it's all loaded at runtime)

OKAY WHAT DOES THIS MEAN

@javlaks I know this sounds stupid, but can you back up your settings and reinstall? Maybe it just botched the install?

I did it but the issue is still present, same error. I had to rollback to Win11_1.14.1963.0

Yes, the computer have some security options enabled by the company, but the weird thing is that previous versions work fine in the same computer, only the latest gives me this error

Note: Presumably there are weird bits set on a page in the DLL giving it invalid permissions (like, write+execute), but what, that should never happen.

If we did ship a binary that got compiled wrong, I'm sure we'll hear a lot more about in this thread soon 😨

No significant difference in DLL headers:

I wonder if it could be an error coming out of loading MUX.dll...

@javlaks do you happen to know which settings they've enabled?

Would you be able to check this one in the Advanced System Properties?

Crap.

How about this, from PowerShell?

get-ciminstance win32_operatingsystem | fl DataExecution*

Huh, that's what I'd expect there. Any chance this just went away/? I don't know if we had any leads left, to be honest. And we haven't heard any other similar reports since. I legit have no idea what this could be other than cosmic bit flip.
