I also faced the similar question in the past. I used the following steps to diagnose and try to solve this issue:

1. Check the Visual Studio 2015 System Requirements to see if your environment meet the requirements. If it doesn't meet requirement, you might need to upgrade it.
2. I saw your screenshot, the error code shows "could not find App.g.i.cs file". You could try to Clean and Rebuild(you can open your project in file explore and find "obj" folder, delete it and Clean and Rebuild your project) to see if it will work.
3. Close your Visual Studio and restart it to see if it will work.
4. Create a new blank UWP project to see if it will work.
5. Try to repair your Visual Studio
