Sometimes Graph module will get scrambled and some commands are working and some are thowing errors. I also needed to have Graph Beta module for one specific need and those commands run as administrator and running as the specific account (to remove currentuser scope versions too) fixed the headache (first line uninstalls all graph modules, second one installs normal Graph module and third line installs the Beta version of Graph module):
Get-InstalledModule Microsoft.Graph* | Uninstall-Module -AllVersions -Force
Install-Module Microsoft.Graph -Scope AllUsers -Force
Install-Module Microsoft.Graph.Beta -Scope AllUsers -Force
