App manager don't show up on emulator

I followed instructions on how to install the emulator and its working fine on WebOS 4.0, 5.0 and 6.0.
The only problem is that when I want to install a app, the app manager window don’t show up after clicking on Menu > App Manager.
There is not a visible error.

I had the same problem. Running on Windows.
No error is displayed, it simply won’t open

App Manager is based on the CLI. Please check if you have installed the CLI properly. Thank you.
