Exception thrown: 'System.IO.FileNotFoundException' in mscorlib.dll when trying to call WCF Service

Question

I'm trying to call a WCF Service however when I call the service in VS2019 Debug Mode, it just closes the debugging process and I see this in my debug log:

Does anyone know why this code might be happening? This solution consists of two projects: 1 console app and a class library both built in .NET Framework. The console app creates a class object from the class library and then calls functions within those classes. However when I call any function in any of the classes, my debugger is immediately closed and that above info is logged into the debug output. However, I know for a fact that the services work because in a separate solution that consists of just the console app, I can call the services fine and they all return the correct values and I can also use SoapUI to send calls to them directly. I believe this has something to do more with Visual Studio and not actually my code. Does anyone know of what the issue possibly could be?

I fixed the problem. In some of my async functions, instead of using the keyword await during a function call, I had to append .GetAwaiter().GetResult() to the function instead. I don't know why this solved the problem, but it did...
