How to Use Group Managed Service Account (GMSA) as a service account for SQL Server 2022

Help please! I have a manual install of SQL 2022 built with the service running as the built in account. I now want to change the service to run as the group managed service account that I now have (i.e. after the instance had been installed). Changing the Log On as in Configuration Manager, I am getting - *The request failed or the service did not respond in a timely fashion. Consult the event log or other applicable error logs for details* but I don't have any helpful information in the logs. Has anyone had this experience? Is there a problem with using gmsa to login manually as I'm trying to do? If so, what is the way round it? How can I change the already installed instance to run with the gmsa? Thank you
