LibGit2Sharp.NameConflictException: failed to write reference 'refs/heads/feature/gitymltest': a reference with that name already exists.

[Softhies]

Describe the bug
exceptions success when running a on azure devop build step gitversion/execute:

LibGit2Sharp.NameConflictException: failed to write reference 'refs/heads/feature/gitymltest': a reference with that name already exists.

Unfortunately, it does not occur locally and powershell on buildserver agentserver but on the Azure DevOps build server/ pipeline.

i am lost, is there a solution?

Please have a look through #864 and #2593 which seems to be duplicates of this.

[HHobeck]

Please check the preview version of git version (currently it is the 6.0.0-beta.3 version) and check whether the problem is solved or not.

Thank you very much.
