Virtual path maps to another application

First, I'm not sure if I am in the correct Forum please direct to proper forum if it is wrong.

I'm am getting the following error when I run my VS2019 WCF app. (Note it was originally written in VS2019)

The virtual path '/MyApp/MyService.svc' maps to another application, which is not allowed.

Now, the app was working before, I think I upgraded to VS 2019 16.11.35 and this issue started to occur but I'm not sure. I have IIS 10 Express installed. I am lost why this is happening now. Can anyone offer insights or solution to this issue?

Thank you!
