[IsraaAbdelghany9]

I using Ubuntu 22.04 only Gazebo11 classic GUI is working neither ignition nor Hurmonic I have deleted everything related to the classic version to see if it is the problem but nothing happend the GUI of the harmonic appear which you can choose whic sdf file you want and when I hit run it fails and print the GUI is not responding and if I run it from the terminal it stays a little bit printing that kind of message wait message then it prints also the GUI is not responding ....... I found someone talking about the firewall and locale setting but nothing , also adding that line to the .bashrc -> export GAZEBO_RESOURCE_PATH=/usr/share/gazebo-harmonic
but also nothing happeded do anyone have any idea what is the problem ...

when I run the comand too:

gz service -s /gazebo/worlds --reqtype gz.msgs.Empty --reptype gz.msgs.StringMsg_V -r 'unused: true' --timeout 2000

it prints out service time out
