Is here someone faced with the same issue? Please help me

Start by reproducing Restore-PowerBIWorkspace after listing the deleted workspace with Get-PowerBIWorkspace -Scope Organization -Deleted. Review the Organization-scope warning, the POST request shown by Resolve-PowerBIError, and the RestorePowerBIWorkspace stack-trace entry point. Done means the reported restore request succeeds or the unsupported condition is clearly documented.
