Hi ROS Team,

I notice today one issue regarding RVIZ.
ROS2 RVIZ is terminated with segfault on Ubuntu 22.04 LTS and Humble ROS distro.

This is not happened sporadically, occurs quite often.

Thanks for the report! Would you be willing to provide a reproducible example? What is RViz visualizing when the crash happens, and what inputs (if any are being given to it?) Otherwise if you're willing to build from source a stack trace would be very helpful in resolving this.
