Hi. Sorry for all mistakes, English is not my native language. I managed to load in gazebo my map and robot model, but after it is loaded I receive following error:

[INFO] [ros2-5]: process started with pid [2622]
[gzserver-1] Segmentation fault (core dumped)

Gazebo window is still working but drop down list Model from World tab is not working. Appreciate any help
