Unable to upgrade to UE4.20 from 4.19

I have recently used UE4.19 and I was able to run my project properly. Then I tried to upgrade the project to UE4.20 and keep getting error module are missing, when I try to build them it says to rebuild from source.Below are the error I have been getting from the VS2017 error list.

The project could not be compiled. Would you like to open it in Visual Studio?
