gazebo-gui-3 process has died

edit

I'm using ROS noetic on Ubuntu 20, trying to run the command "roslaunch package spawn.launch" after doing "source /opt/ros/noetic/setup.bash" and "source devel/setup.bash". I get the following:

"[INFO] [1603291907.439879200]: waitForService: Service [/gazebo_gui/set_physics_properties] has not been advertised, waiting..

Aborted (core dumped)

[gazebo_gui-3] process has died [pid 6432, exit code 134, cmd /opt/ros/noetic/lib/gazebo_ros/gzclient __name:=gazebo_gui __log:=/home/araff/.ros/log/ed9e1bec-13ac-11eb-94b0-80ce6246ff47/gazebo_gui-3.log].

log file: /home/araff/.ros/log/ed9e1bec-13ac-11eb-94b0-80ce6246ff47/gazebo_gui-3*.log"

After which the process gets stuck. I've tried uninstalling ros and reinstalling, nothing seems to work. As a sidenote, when I try to simply run the command "gazebo", I don't get any error messages but nothing actually happens.
