Describe the bug
Hi, @adamdbrw @pijaro if you could help me to solve this issue I would be very appreciated

I'm trying to setup AWSIM-Lab as Unity Project on Windows.
Following this issue we found out that ros2-for-unity has missing library file when we try to run it under Windows 11 and AWSIM-Lab as Unity Project setup.

To Reproduce
Steps to reproduce the behavior:

1. Follow AWSIM-Lab Setup Instructions for Windows
2. Run the demo in Unity Editor
3. Open Unity Console
4. See error
