Internal ArgumentNullException during Repository.Reset

We have a tool that regularly runs on a repository to migrate changes between several different repositories. As a part of the process, we do a soft reset of a submodule, which periodically (around one time per week) fails with an ArgumentNullException:

Unhandled Exception: System.ArgumentNullException: Value cannot be null.
Parameter name: SafeHandle cannot be null.
    mscorlib.dll!System.StubHelpers.StubHelpers.SafeHandleAddRef(System.Runtime.InteropServices.SafeHandle pHandle, ref bool success) Line 1664
    LibGit2Sharp.dll!LibGit2Sharp.Core.Proxy.git_reset(LibGit2Sharp.Core.Handles.RepositorySafeHandle repo, LibGit2Sharp.ObjectId committishId, LibGit2Sharp.ResetMode resetKind, ref LibGit2Sharp.Core.GitCheckoutOpts checkoutOptions) Line 2615
    LibGit2Sharp.dll!LibGit2Sharp.Repository.Reset(LibGit2Sharp.ResetMode resetMode, LibGit2Sharp.Commit commit, LibGit2Sharp.CheckoutOptions opts) Line 1002
    LibGit2Sharp.dll!LibGit2Sharp.Repository.Reset(LibGit2Sharp.ResetMode resetMode, LibGit2Sharp.Commit commit) Line 985

Unfortunately, I do not have a specific repo; every time this happens a rerun works properly again.

Version Consumed: 0.22. I'm not aware of this happening in an earlier version, but we had enough bugs in the tool itself that it's quite possible we never picked this up in the noise.

Inizia con Repository.Reset e la chiamata Proxy.git_reset mostrata nello stack trace, usando il contesto LibGit2Sharp 0.22 indicato. Analizza come vengono passati l’handle del repository e gli input del soft reset durante i reset dei sottomoduli; l’issue non fornisce un repository riproducibile, quindi il lavoro è completato quando avrai isolato la causa intermittente del null handle e verificato che il reset non generi più eccezioni.
