Hi @Khal1L,
That’s good news for the Ethernet connection.
To be sure there is no issue with the settings of your Quest 3S, could you test on another app where there is stereo vision, and not just the Quest home environment ?
Also, it can be an issue of Gstreamer installation : did you use the installer, and did GStreamer install correctly when you installed the app? You can try to reinstall the app to be sure.
Otherwise you can download it directly : https://gstreamer.freedesktop.org/download/#windows, then check that the environment variable PATH contains C:\gstreamer\1.0\msvc_x86_64\bin (default installation) For that, look for “Edit the system environment variables” in the Windows search bar. Then, click on Environment variables. A new window shows up : double click on “Path” in the user variables. If you don’t see the gstreamer variable, select “New” and add the pathway above. 
Reboot after installation.
About the logs, I’m sorry I don’t see the mail with the new logs; I have the last one but where we can’t see the start of the error unfortunately. (the log about self.x_vel_goal is not a concern)
