Did you build from source or install using the Debian package?

I've installed the open3d-app-0.11.1-Ubuntu_20.04.deb on Ubuntu 20.04.1 LTS, I've got same error :

Note that open3d-app-0.11.0-Ubuntu_20.04.deb works fine

Also it seems the newest deb package open3d-app-0.11.1-Ubuntu_20.04.deb create wrong path to Open3D viewer binary in the desktop entry so we cannot launch it from gnome.

The correct path should be /usr/local/bin/Open3D, but in /usr/share/applications/Open3D.desktop it is: /usr/local/bin/Open3D/Open3D

I encountered the same problem, but my system is 18.04. I installed the app directly, not compiled. Is there a solution? thank you
