I'm seeing this on VS 2022 as well.

I'm running into the same issue trying to debug msbuild when running from VS.
Is there a workaround that would allow me to create binlogs from MSbuild processes launched by Visual Studio ? (Environment variables, passing flags into devenv.exe, ..)

[ktaeleman]

Looks like there is a workaround by setting the MSBuildDebugEngine environment variable to 1.
