System.TypeInitializationException thrown on MacOS

[victorlazaro]

I am running into this error when running nuget restore on a Mac:

This is with the -NonInteractive flag. Without the flag, the same error occurs before I'm prompted for my credentials. I tried using previous versions of the netfx plugin, but no luck.

I am on a MacOS 15 using dotnet version 8.0.403. Please let me know if any more info is needed.

@victorlazaro - I have yet to reproduce this - which version of msbuild are you using? Thanks
