Unable to get Windows Admin Center v2 (2410) to work at all

So I had the old Windows Admin Center installed and working, using Windows Credentials in my domain.  There were a few issues with some of the menus that just would not work like they should, but normal updates to Windows Admin Center would fix it for a little while.  They release Windows Admin Center v2 and I do an install of that with the old Windows Admin Center still installed.  I am able to use the existing cert and could log into Windows Admin Center and see all the machines.  Though after the Windows Admin Center v2 install, always got a ajax 500 error, when trying to connect any machine with Windows Admin Center, even the local machine.

This past week, uninstall Windows Admin Center off of the Windows 11 computer that I had been using, both the v2 and v1 versions of it.  I then reboot and install the Windows Admin Center v2, using custom setup.  Prior to this I went into certificates on the computer and requested a web server cert for this computer using the name of the computer in DNS.  My AD CS provided the new cert and I installed it as a computer certificate, under personal.  Afterwards I then assigned Network Service full control of the certificate.  I selected that certificate during the Windows Admin Center v2 setup and selected Windows authentication, and left everything else as default.

Windows Admin Center installs and I launch it, I get to the prompt for username and password from Windows, enter the correct domain credentials and it repeatedly loops through.  I went 17 tries and was never able to get into Windows Admin Center.  Never got anything saying that I couldn't login, just repeatedly ask for the credentials.

So how do I get this blasted thing to work?  Uninstall it again, install the Windows Admin Center v1 then the v2 and try and deal with the ajax 500 issue?  Nuke the entire computer and install it from a fresh Windows 11 install?  Or just give up and always use remote desktop to manage all the servers, which Windows Admin Center v1 helped me half avoid?
