This might have nothing to do with the error, but there is a similar error reported [in this issue](https://github.com/dotnet/fsharp/issues/4507) for the fsharp project.

I have received two more error reports which are basically the same as this issue. On 4-August-2020 ``` System.NullReferenceException: Object reference not set to an instance of an object. at...

And another on 5-April-2021 ``` System.NullReferenceException: Object reference not set to an instance of an object. at Microsoft.VisualStudio.Differencing.Package.DiffPackage.DiffFiles(StringleftFile, String rightFile, IVsWindowFrame&windowFrame, UInt32 options, String caption, String tooltip, String leftLabel, String...

I have uploaded a new version (1.0.7) which I hope will fix this. The annotate view is now an normal editor window, using a custom margin. The editor is read-only,...

And a similar error from the same user on 30 September 2020 ``` System.Runtime.InteropServices.COMException (0x80004005): Invalid node '114'. at Microsoft.DataWarehouse.VsIntegration.Hierarchy.Hierarchy.NodeByItemID(UInt32 itemID) at Microsoft.DataWarehouse.VsIntegration.Shell.Project.FileProjectHierarchy.FileProjectNodeByItemID(UInt32 itemid) at Microsoft.DataWarehouse.VsIntegration.Shell.Project.FileProjectHierarchy.GetSccFiles(UInt32 itemid, CALPOLESTR[] fileNames, CADWORD[]...

I have also received this Email report on 4-June-2020 which appears to be identical to the above error: ``` System.InvalidOperationException: Collection was modified; enumeration operation may not execute. at System.ThrowHelper.ThrowInvalidOperationException(ExceptionResource...

And this very similar error report on 13-June-2020 ``` After "refresh status" at solution level just after the creation of the repository. Thank you System.InvalidOperationException: Collection was modified; enumeration operation...

And this one on 13.October.2020 ``` System.InvalidOperationException: Collection was modified; enumeration operation may not execute. at System.ThrowHelper.ThrowInvalidOperationException(ExceptionResource resource) at System.Collections.Generic.Dictionary`2.ValueCollection.Enumerator.MoveNext() at Ankh.Scc.OpenDocumentTracker.RefreshDirtyState() at Ankh.UI.PendingChanges.PendingCommitsPage.RefreshList() at Ankh.UI.PendingChanges.Commands.RefreshPendingChanges.OnExecute(CommandEventArgs e) at Ankh.Commands.CommandMapItem.OnExecute(CommandEventArgs e)...
