Windows Clone Artifact doesn't work - chocolately error

Recently, the windows-clone artifact has stopped working for our team. We receive the following error

**WARNING: An existing Chocolatey installation was detected. Installation will not continue.

For security reasons, this script will not overwrite existing installations.

Please use choco upgrade chocolatey to handle upgrades of Chocolatey itself.
Error! Git clone failed with exit code 128. Please see the log file: C:\Packages\Plugins\Microsoft.Compute.CustomScriptExtension\1.10.10\Downloads\6\PublicRepo\master\78b42624b14781087e45928851ee5f5b5b65c29c\Artifacts\windows-clone-git-repo\scripts\GitEnlister-2021-05-17-21-21-53\Logs\GitClone.err**

This is very problematic for our team as it prevents our daily Azure VM deployments from succeeding since we fail on the clone step.

Is this a known issue? Is there a workaround?

Thanks,

Courtney
