Unable to load native module

I have a very small python script that returns the error.

I have packed this up two ways and get the same error. I have installed the packages directly to the folder, and then zipped. And I have also created a virtual environment, installed the packages and then zipped. I still get the same result.

I have had a look but couldn't find a solution to this.

Does anyone know why this isn't working?

Error code below:
