[reza0ramesh]

hi , i have problem using gazebo_ros package , when i want to launch a file with gazebo_ros pakage like :
ros2 launch gazebo_ros gazebo.launch.py
it doesnt work and there is not any error either :
[INFO] [launch]: All log files can be found below /home/reza720/.ros/log/2024-11-02-19-20-40-342948-reza720-GF63-Thin-10SC-5785
[INFO] [launch]: Default logging verbosity is set to INFO
[INFO] [gzserver-1]: process started with pid [5786]
[INFO] [gzclient-2]: process started with pid [5788]
its all i see in terminal the point is i can launch an empty gazebo world with writing gazebo in terminal but i cant launch files and sometimes i even have error such as :
[INFO] [launch]: All log files can be found below /home/reza720/.ros/log/2024-11-02-19-13-40-486219-reza720-GF63-Thin-10SC-4585
