Description

Reproduction steps

I had a bug report on my project about this.

this is the code that's failing on an M1 chip.

        public static void GitSetup(string solutionDirectory)
        {
            GitBuilder.CreateGitIgnore(solutionDirectory);

            Repository.Init(solutionDirectory);
            var repo = new Repository(solutionDirectory);

            string[] allFiles = Directory.GetFiles(solutionDirectory, "*.*", SearchOption.AllDirectories);
            Commands.Stage(repo, allFiles);

            var author = new Signature("Craftsman", "craftsman", DateTimeOffset.Now);
            repo.Commit("Initial Commit", author, author);
        }
Expected behavior

I should have a new repo created and an initial commit made. This works fine on my intel chip.

Actual behavior

This is the exception that gets thrown

TypeInitializationException: The type initializer for 'LibGit2Sharp.Core.NativeMethods' threw an
exception.

Research direction

Reproduce the failure on the reported macOS 12.1 arm64 environment using GitSetup in Utilities.cs, then inspect LibGit2Sharp.Core.NativeMethods and the call path through NewDomainProjectCommand.cs and NewExampleCommand.cs. Done means Repository.Init and the initial commit complete successfully on an M1 chip without the TypeInitializationException.
