Git LFS Type Initialization Error

I was trying to build some sources from GitHub and got this:

Unhandled exception: System.AggregateException: One or more errors occurred. ---> System.TypeInitializationException: The type initializer for 'Inedo.Extensions.Clients.LibGitSharp.LibGitSharpClient' threw an exception. ---> LibGit2Sharp.EntryExistsException: A filter with the name 'lfs' is already registered

Not sure what was wrong, but I resolved the issue by deleting the temp repo in C:\ProgramData\BuildMaster\Temp\Service\GitWorkspaces and restarting the BuildMaster service.
