Hello,
Was it just the web service domain URL change or the Active Directory domain change? Post the CRM servers installation, AD domain change is not a recommended/good practice.
The supported way to migrate CRM to a new AD domain would be to spin up a new CRM deployment with a SQL server on the new domain and then take the DB copy from the existing domain and restore it to the target domain. Post the restore action, the org can be imported from the new CRM deployment which exists on the target domain.
"Failed to get prev user group information" exception is usually seen when the directory services objects cannot be queried by CRM. What is the exception windows server gives while starting the Sandbox Service? If it is log on exception, ensure that you supply the right credentials for the service by going to the properties then log on.
You may run a server repair which may resolve any machine or AD objects privilege issues by supplying the right CRM services account.
Try the latest SDK tools for CRM which is a part of Dynamics 365 SDK tools and can be downloaded from here using simple PowerShell script ::
https://docs.microsoft.com/en-us/dynamics365/customerengagement/on-premises/developer/download-tools-nuget
If this doesn't work out with the latest Plugin Registration tool, check the plugin registration logs to get more details as the current exception is a bit generic.
Please mark my comments as answered if this helps.
Thanks,
Saurabh
