[Bug] Black screen when launching the Scene Meshing example

[Xuechun-Hu]

I am encountering an issue where the Scene Meshing example displays a black screen immediately after launching the app.

I have verified my setup by compiling and running the Object Tracking example, which works perfectly. This suggests the issue is specific to the Scene Meshing sample or its specific requirements.

The warning is from an old version of the extensions package. After v1.1.0 Scene Meshing was upgraded to public. Please use the latest version v1.2.0
