It sounds like cava hasn't packaged a dll that one of the modules you're using (GD) relies on. For that you'd need to read and understand the documentation for the packager you're using. I don't use cava, this is all explained for pp in the documentation and the links you've already been given.
"I've tried several methods of creating an exe but failed"
You've provided feedback for cava, nothing else. No examples of how you tried to package this with pp. There's nothing anyone can help you with. Spend the time learning to use the tools you've chosen. Links have been provided. If you have an actual problem you want help with read and understand How do I post a question effectively?.
Also, your keyboard seems to have a faulty ? key.
