I know it's a relatively new and unstable application but I figured if anyone has suffered through the issue and solved it then they can help me
The Problem
when I click on the Anbox icon from gnome app drawer it stays in launcher for 5 secs or so and disappears but it doesn't launch
What worked for me is running the session manager then clicking on the icon.
first run session manager by entering this command
and then click on the Anbox icon from launcher
Better way would be to add this service inside Startup Applications
to do that open Startup Applications > Add > in command write
anbox session-managerand you'd be able to use Anbox without running that command on every boot or keeping a minimised terminal windows.
