Getting System.TypeInitializationException Error when scanning from NAPS2.Sdk

[hansaliyad1]

I'm getting the following error when trying to scan from NAPS2.Sdk:

Error in CallStartScanning: System.TypeInitializationException: The type initializer for 'PerTypeValues`1' threw an exception. ---> System.IO.FileLoadException: Could not load file or assembly 'System.Runtime.CompilerServices.Unsafe, Version=4.0.4.1, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

Below is my code. I believe this error is due to a version conflict with System.Runtime.CompilerServices.Unsafe, but I'm not sure how to resolve the conflict.
