I am running into an issue trying to install 2022.1 RTW

When I try to upgrade my Azure DevOps 2022.1 RC to Azure DevOps 2022.1 RTW it takes a VERY LONG TIME, and ultimately stops with an error, but the error is not useful "the intallation did not complete sucessfully".
yet, when I look at the installer logs I see the following

dd_devops_server_20240218201745_001_devops_serverCore:  

MSI (s) (D4:90) [20:33:50:520]: Product: AzureDevOpsCore2022.1 -- Installation completed successfully.

Why am I getting an error?
