"AppxManifest.xml : error APPX0501: Validati on error. error C00CE169: App manifest validation error: The app manifest must be va lid as per schema" when building seed for Windows 10 Mobile ARM

[ghost]

So, I wanted to build the seed for Windows 10 Mobile (Lumia 550), to learn building Cordova apps on Windows 10 Mobile.

Decided to build for Lumia 550, so ARM architecture. Got error - because of some system settings I don't know of, some error logs are mixed english language with my main language, this is my translation:

I don't know a thing about any pattern restrictions, didn't set any pattern by myself. I'd like to build this seed for x64 and ARM Windows 10, to run it on emulator and physical device. Anyone knows solutions?

Cheers!
