MDS fails to create website with error "no master data services instance section exists"

Robson, James 61 Reputation points

I installed SQL Server Developer Edition with Master Data Services. I turned on IIS Express with all of the MDS dependencies. When I open MDS Configuration Manager, it shows a green check mark for IIS, so it thinks IIS is configured properly. When I go to the Web Configuration page, select Default Web Site, create the site, associate it with the database, and click Apply, I get the error "no master data services instance section exists".

I check IIS and it thinks there is a website... Screenshot 2023-04-06 103359

However, I check in the Master Data Services directory under SQL Server, and the web site folder is not created... Screenshot 2023-04-06 103042

I'm running on Windows 10 Enterprise, build 19044.1586 Any idea what's going on?
