Gathering initial app source doesn't load on desktop

I am using Appium Mac desktop version 1.20.2
macOS Big Sur 11.2.3
my device is on Android 10, Samsung a 50

When I start Inspector session, the device begins to open the app, but n the desktop it just keeps on loading saying “Gathering initial app source” … and nothing happens

It works fine on my other Samsung s20+, so anyone knows what can be the problem?
