I install RQt from ROS-Humble but it failed to run with the following error:

Had the same isue. I think the problem is that ament_python packages are not added to AMENT_PREFIX_PATH variable (see this answer). The solution for now is to use buildEnv like in the examples to put all of the ROS packages into a single path.

Thank you for the suggestion, it works now.
