Describe the bug

Using the RestoreSiteCollection command to restore a deleted SharePoint Site Collection that is in the Recycle Bin, restores the Site Collection, but not its associated Group.

Steps to reproduce

01 - Create a new Team Site Collection using the SharePoint Admin Center (Sites -> Active sites -> Create -> Team site -> give it a name and an administrator)
02 - Review that the new Site Collection do have an associated Group (Microsoft 365 Admin center -> Teams & groups -> Active teams & groups -> a group with the same name as the Site Collection should be visible in the list of Groups)
03 - Delete the Site Collection using the SharePoint Admin Center (Sites -> Active sites -> select the created Site Collection from bullet 01 -> open the menu with the ellipse button (...) -> Delete -> check the check box "Delete the group [GroupName] and all its resources" -> Delete)
04 - Review that the Site Collection is indeed deleted (SharePoint Admin Center -> Sites -> Deleted sites -> the Site Collection must be in the list)
05 - Review that the associated Group is indeed deleted (Microsoft 365 Admin center -> Teams & groups -> Deleted groups -> the Group with the name of the deleted Site Collection should be visible in the list)
06 - Open PowerShell, use the method "Create" or "CreateAsync" to make a PnPContex (authenticate the user) using an Azure App Registration. Set the "SetMinimumLevel" to "LogLevel.Debug" to see verbose logging of the process
07 - Run the next command to restore the Site Collection:
myContext.GetSiteCollectionManager().RestoreSiteCollection(new Uri("https://[domain].sharepoint.com/sites/[SiteCollName]"));
08 - Review in the log shown in PowerShell that there are no errors in the processing
09 - Review in the SharePoint Admin center that the Site Collection is restored (Sites -> Active sites -> Create -> Team site -> the deleted Site Collection should be back in the list)
10 - If you click on the Site Collection name in the list, you will see a message in the properties window saying "We couldn't find the Microsoft 365 Group connected to this site."
11 - Review if the Group is restored using the Microsoft 365 Admin center (Teams & groups -> Active teams & groups -> the Group is not visible in the list)
12 - Review that the Group is still in the deleted groups (Microsoft 365 Admin center -> Teams & groups -> Deleted groups -> the Group with the name of the deleted Site Collection will still be visible in the list)

Expected behavior

The RestoreSiteCollection must restore both elements: the Site Collection and its associated Group. Now it restores only the Site Collection, not the associated Group

Thanks for using PnP Core SDK and reporting this issue @gavdgavd , will take a look and report back.

@gavdgavd : I'm working on an update that will use Microsoft Graph to first restore the group before the actual site collection is restored. Will report back once that's done

@gavdgavd : a fix has been pushed and will appear in the next nightly build (version 1.6.8 or higher). With this fix when restoring a site collection that has a group connected to it the code first tries to restore the Microsoft 365 group. I'll close this issue, but don't hesitate to either re-open or create a new one when you still have issues. Thanks again for using PnP Core SDK and providing feedback.
