Since I am having virtually the same problem (without the Qt notification), I would like to take up the answering from here. I installed ROS2 from source and have it in ~/ros2_ws. I have uploaded screenshots of my problem setting. There is no ~/ros2_ws/bin/rviz2, only a ~/ros2_ws/build/rviz2 which is a directory. What do you mean by <path_to_ros2> then? Do you have any other ideas why this happens?
Thanks a lot!
