I'm doing the "navigation2 stack tutorials" and I'm still at the beginning. When I run "ros2 launch nav2_bringup tb3_simulation_launch.py" in a terminal, the simulation opens up in gazebo/rviz and I can move the robot during some time before it gets stuck and doesn't respond to the commands even if I pause or reset the simulation.
The only way to make it works again is by killing the nodes and by starting the launch file. Did anyone else faced this problem and how did you manage to solve it ?
Thanks
