as discussed above, you need to install .net core packages. For example, I'll share my case, where I configured server for .net core 2.2.3. It should look like:

enter image description here

And set app pool as:

.NET CLR Version - set value to 'No Managed Code'

Managed pipline mode - set value to 'Integrated'

Let me know if you still face issues.
