This is really a show stopper for us, if anyone can help solve this, please update

It looks like your ROS distro is not visible. In case of standalone version, ROS libraries should be shipped with the Unity package. Are you building from source, or using a release package?

@adamdbrw I used: Ros2ForUnity_humble_standalone_ubuntu22.zip

Unfortunately, our support for the project is very limited at the moment, as it just works for one project we use it for and all the other projects are on Open 3D Engine, much recommended as free Unity3D alternative

Perhaps @pijaro could help you as he prepared the build

The second error may be connected to the issue (calling get_data from non-main thread).

Can you confirm, that running everything from the main thread still throws the ROS 2 error?
