I'm using the latest update: https://aka.ms/PowerShell-Release?tag=v7.2.4

Sorry for not getting back to you earlier but it comes back with this error:

I just installed 7.2.4 and it does work for me.
I remember I got similar, or even the exact same error, when I tried to call this method from within MSBuild (building a .csproj in Visual Studio, which executed PS script), but didn't bother to investigate what's the issue.
