What did you do?

Ran v main.v from the command line.

// main.v
import ui

struct App {
mut:
    window     &ui.Window = unsafe { nil }
}

fn main() {
    mut app := &App{}
    app.window = ui.window(
        width: 600
        height: 400
        title: 'V UI Demo'
        children: [
            ui.row(
                margin: ui.Margin{10, 10, 10, 10}
                children: [
                    ui.column(
                        width: 200
                        spacing: 13
                        children: [
                            ui.label(
                                text: 'Hello'
                            ),
                        ]
                    ),
                ]
            ),
        ]
    )
    ui.run(app.window)
}
