Exception on Azure DevOps Mac in Nerdbank.GitVersioning.Tasks.GetBuildVersion

[Eilon]

Something similar was previously reported here: #306

But that was fixed ages ago, and I'm running the latest RTM version: https://www.nuget.org/packages/Nerdbank.GitVersioning/3.1.91

I'm running this on Azure DevOps on a Mac build and it gets this exception and then seems to hang (at least ~45min; I then cancelled the build):
