Following my suspicion of IIS, I logged in as the (Built-in) Administrator and used Server Manager to remove IIS and its dependencies completely, and then ran the installer again and now it works. Looking at the Server 2019 image I have (installed via WDS), it has IIS enabled by default, so IIS was corrupted from the start.

I am now able to log into the web ui without issue.
Thanks for your help diagnosing this, if someone finds this in the future, I hope it helps!

@theopenem_admin Fantastic! Works like a charm - thanks!

Can you post your com server multicast.log

@theopenem_admin So...I'm not sure who to be upset with, myself, or the people who made this image... As it turns out, some genius in the base image UNINSTALLED .NET frameworks...

Thanks for your help, I really appreciate it. After installing .NET Framework 4.8 it installed just fine on Server 2016.
