UE4 suddenly unable to open source files

I have been trying to learn Unreal over the past 3 weeks and have run into an odd issue which I cannot find elsewhere. When I was learning to use c++ with cameras and pawns as is found in the documentation I was able to compile with all of the defaults set. I wanted to decrease the overall size of the build file so I started to remove assets which held no dependencies. I am now no longer able to compile any of the code through either VS2018 nor UE4. Here is part of the multi-hundred line error.

I don’t even know where to begin with such an overwhelming issue so anything that may lead to a solution would be helpful. Thank you for your time and consideration!

Create a blank C++ template and migrate your game to that. Worth a shot. (don’t forget to copy your config folder over seperately).
