Failed to bind to address https://localhost:7090 - The server mode SSL must use a certificate with the associated private key - iis

Question

We've been trying to fix a developer's machine with all sorts of HTTPS issues running:
Windows 11
Visual Studio 2022
A .NET 7 C# MVC application
When we attempt to start debugging in Visual Studio, it fails on app.Run() with the following exception:
System.IO.IOException
HResult=0x80131620
Message=Failed to bind to address https://localhost:7090.

This exception was originally thrown at this call stack:
[External Code]
Inner Exception 1:
AggregateException: One or more errors occurred. (The server mode SSL must use a certificate with the associated private key.) (The server mode SSL must use a certificate with the associated private key.)
Inner Exception 2:
NotSupportedException: The server mode SSL must use a certificate with the associated private key.
We recently reinstalled IIS and Visual Studio to get the IIS Express Development Certificate regenerated on the machine. It was then exported from Personal->Certificates and imported into Trusted Root Certification Authorities->Certificates.
We also tried using dotnet dev-certs https to generate a certificate as well. It does say:
A trusted certificate was found: 5DA2.....AFAC - CN=localhost - Valid from 2022-12-09 15:33:53Z to 2023-12-09 15:33:53Z - IsHttpsDevelopmentCertificate: true - IsExportable: true
When we deploy the .NET 7 application and run it through the local IIS, the page loads, but some static content files (like jquery.js and site.css) will error out with ERR_CONNECTION_RESET and sometimes the page will just load forever without timing out. The Event Viewer reports nothing out of the ordinary. And everything works fine under HTTP.
