Gazebo services call [/shadow_caster_material_name] and [/shadow_caster_render_back_faces] time-out, making Gazebo and ROS launchers unusable

edit

Setup: Ubuntu 20.04, ROS 2 Galactic, Gazebo (11.10.1-1~focal)

With the update to the gazebo11 (ver 11.10.1) in the last ROS 2 Galactic sync my launch files and Gazebo overall stopped working correctly (services are timed out).

After starting gazebo --verbose I got:

Reverting to the old version of Gazebo packages didn't help, but I am not sure if I did it correctly too (maybe I have missed some dependent ROS packages). I have used:

sudo apt-get install gazebo11=11.9.0-1~focal gazebo11-common=11.9.0-1~focal gazebo11-plugin-base=11.9.0-1~focal libgazebo11=11.9.0-1~focal libgazebo11-dev=11.9.0-1~focal

Gazebo and launcher still won't work even after that. I tried to reinstall everything, Gazebo, ROS2, my GPU drivers (latest recommended nvidia-driver-510, then switched to last working nvidia-driver-470 - still no luck).

It starts with empty.world scene, but any launcher (mine or from Nav2 repository and nav2_bringup package, branch" galactic, commit: 4bfedb8) cannot call any services. In the second terminal I have everything sourced and ros2 topic list doesn't show me any of the topics of Turtlebot3 robot placed in the Gazebo.

When starting gzserver --verbose I am getting standard output, gzclient --verbose gives me every time the same timed-out error.

I put this issue there already + I haven't found anything more than some issues of the problems with Ogre3d about this kind of services timing out...
