PrintNightmare.dll crashes

[65535a]

Hi!

I keep getting heap corruption errors in my lab machine while trying to launch the exploit through Beacon. I think this might be a matter of compiling and therefore I've tried to compile the binary in both VS2022 and VS2019, trying both /MD and /MT runtime libraries. I'm not too familiar with debugging C programs so this is the best I can do for now.

So, what's the specific setup needed to compile the binary?

The error from Windows log:
