I cannot save my world after, save as Gazebo freezes and there is no error shown in the terminal. if I minimize the gazebo once then the save window pops up. but if I click on anything in that window it doesn't work. can you help

Did you launch gazibo with sudo?

If you are adding "a lot" of walls, it may happen. I would then suggest to build your model in blender and then export. I always had gazebo crash on me whenever I had large environments.
