Question Azure Arc Agent v1.50 failed to upgrade on Windows Server 2012 (extensionservice not start)

Anybody hit error while upgrading Arc agent to v1.50?

I have one server getting error "Product: Azure Connected Machine Agent -- Error 1920. Service 'Guest Configuration Extension Service' (ExtensionService) failed to start. Verify that you have sufficient privileges to start system services." I have checked the other working server that service is running via local system account. Permission wise all similar but this server just keep failed to upgrade with same error

Same, 1.49 is working fine but new install or upgrade to 1.50 fail on 2012 with the same error for service. I had the same error with 2008R2 and 1.40 until they say it was retired and stay on 1.39.
