Robot Model not loading in gazebo

[2vin2vin]

I am using ubuntu 22 and ros2 humble
I have been working with simulating linorobot2 and it worked earlier and out of nowhere today the model doesn't spawn.
I have checked even with turtlebot3 and the model doesn't spawn
All of them worked earlier, without any changes made to the launch file now they don't
The issue should possibly be with gazebo

As the gazebo has launched without the robot, I tried to spawn the robot separately and got this error
ros2 run gazebo_ros spawn_entity.py -file /home/brahms/husky_ws/src/linorobot2/linorobot2_description/urdf/robots/4wd.urdf.xacro -entity linorobot2

[ERROR] [1738147703.862745864] [spawn_entity]: Spawn service failed. Exiting.
[ros2run]: Process exited with failure 1

Then i tried out
ros2 topic list
/parameter_events
/rosout

Gazebo is still open, it seems like gazebo did not start with ros
but in my launch file I am starting it with
ExecuteProcess(
cmd=['gazebo', '--verbose', '-s', 'libgazebo_ros_factory.so', '-s', 'libgazebo_ros_init.so', LaunchConfiguration('world')],
output='screen'
),

I am really confused on how to get this working
