-WaitMutex- error sufficient right needed to access the file

solved the bGenerateOverlapEvents error… now dealing with two more errors

Error Code
E0020 - Solved
MSB3075
(Refer to above pictures on the error log)

Update : Also solved the E0020 by adding this line on my VertexFactory.h file

#include "Runtime/Renderer/Public/MeshDrawShaderBindings.h"

So now left with the MSB3075
