"corber start" hangs on ember build

[PowerP]

Hey,

my corber start command hangs on 90% of the time.

corber start
Browserslist: caniuse-lite is outdated. Please run next command `npm update`
Corber Starting
? Select a device/emulator android device - Pixel_3a
WARNING: corber
Your corber/cordova/config.xml file has set the following flag:

This is necessary for device live-reload to work, but is unsafe and should not be used in production.

The option '--CORBER_PLATFORM' is not registered with the 'serve' command. Run `ember serve --help` for a list of supported options.
- building...

And that's it. No error, nothing.
Normal ember commands and builds work fine.
I use ember-deploy.
I use Windows 10.

Any idea?

Cheers,
Pi
