Gazebo crashes when selecting robot model

I am trying to create a robot to simulate ros code in Gazebo, but whenever I load it into gazebo and click on it, Gazebo crashes. After viewing rqt_graph, I can see that only the gui crashes. I commented out most of my robot so all that remains is a box, so I don't think it's the model. The gui also doesn't produce a log. I've tried this on another machine and the same thing happens. I am running gazebo 9 installed with ros melodic using an Ubuntu Virtualbox. I am launching gazebo with a launch file.

UPDATE:

I have reduced the model down to the chassis. This is the model if it helps.

Can you try launching with extra_gazebo_args:="--verbose" to see if any helpful messages are printed?

All it mentions is the ogre error found above the red in the image.

I've seen that Ogre error when some link dimensions are zero. Could you check your robot's spec? Also, which Gazebo 9 minor version are you using?

I'm using 9.0.0, and link dimensions are all positive.

I suspect you may be running into an issue that was fixed by this PR:

You could try upgrading to a later Gazebo 9 version following these instructions: http://gazebosim.org/tutorials?tut=install_ubuntu&cat=install

Do i need to uninstall Gazebo in order to upgrade?

Hi! I'm stuck at the same issue. How did you get it working?
