My NativeScript Angular project, on which I've been working for some time, stopped compiling about one week ago, error message is Build failed with error code 2.
But, on another machine project compiles normally!
On both computers I use
NativeScript Sidekick, latest version: 1.19.1-v2019.8.1.2,
NativeScript CLI version: 6.0.3,
CLI extension nativescript-cloud version: 1.18.1,
CLI extension nativescript-starter-kits version: 0.3.5
I've reinstalled node, tns and Sidekick, I've deleted cloud cache, I've created new Telerik account in order to try to avoid anything cached on the cloud.

[19-08-21 08:57:33.894] (CLI) # tns prepare
[19-08-21 08:57:33.894] (CLI) ### Description
[19-08-21 08:57:33.894] (CLI) Starts a Webpack compilation and prepares the app's App_Resources and the plugins platforms directories. The output is generated in a subdirectory for the selected target platform in the platforms directory. This lets you build the project for the selected platform. You must specify the target platform for which you want to prepare your project.
[19-08-21 08:57:33.894] (CLI) When running this command the HMR (Hot Module Replacement) is not enabled by default. In case you want to enable HMR, you can pass --hmr flag.
[19-08-21 08:57:33.894] (CLI) ### Commands
[19-08-21 08:57:33.894] (CLI) ┌─────────┬──────────────────────────┐
[19-08-21 08:57:33.894] (CLI) │ Usage │ Synopsis │
[19-08-21 08:57:33.894] (CLI) │ General │ $ tns prepare <Platform> │
[19-08-21 08:57:33.894] (CLI) └─────────┴──────────────────────────┘
[19-08-21 08:57:33.894] (CLI) ### Arguments
[19-08-21 08:57:33.894] (CLI) <Platform> is the target mobile platform for which you want to prepare your project. You can set the following target platforms.
[19-08-21 08:57:33.894] (CLI) * android - Prepares your project for an Android build.
[19-08-21 08:57:33.894] (CLI) * ios - Prepares your project for an iOS build.
[19-08-21 08:57:33.894] (CLI) ### Options
[19-08-21 08:57:33.894] (CLI) * --hmr - Enables the hot module replacement (HMR) feature.
[19-08-21 08:57:33.894] (CLI) * --force - If set, skips the application compatibility checks and forces npm i to ensure all dependencies are installed. Otherwise, the command will check the application compatibility with the current CLI version and could fail requiring tns migrate.

And I've pinned the suspect - this started after I installed Angular CLI, but now even if I uninstall Angular CLI, error remains and I cannot use NativeScript!
