DuplicateKey: There is already a duplicated entity

The following error is encountered recently - this wasn't occuring a couple of weeks ago, so permissions should be OK (I think). The target environment is my lab, so not many Azure AD configuration changes.

The export is running on PowerShell Core on Windows or macOS with AzureADExporter 1.0.957478.

This is the currently exported data at `IdentityGovernance/EntitlementManagement/Settings/singleton/singleton.json. Note that the result of this error is that this file is not exported:
