Developer technologies | Universal Windows Platform (UWP)
A Microsoft platform for building and publishing apps for Windows devices.
I am not sure what happened, but the problem seems to have resolved itself. I can debug the app.
Hanging on installing a missing framework

This morning I started a new UWP project to test something. This is a very simple project. I have a textbox, button and textblock. That's it. I've added MVVMLight to it. I built it next. That worked fine. Then I've tried to debug it. That's where it hangs, for 15 minutes and more with this message in VS 2019's Output window:
"Creating a new clean layout...
Copying files: Total 7 mb to layout...
Checking whether required frameworks are installed...
Framework: Microsoft.NET.CoreFramework.Debug.2.2/X86, app package version 2.2.28529.0 is not currently installed.
Installing missing frameworks..."
Clearly installing Microsoft.NET.CoreFramework.Debug.2.2/X86 is hanging. What's the issue? Why is it doing this?

How did you debug your app? Do you mean when you directly run it, it will hang on? If you don't add MVVMLight and do the same behavior, will the same issue occur?

I tried to upload a .zip file of my VS solution, but I can't upload .zip files to this website.
