This class seems to be duplicated in your project.

    protected $options = [
        'mask' => '99999999999',
    ];

    public function render()
    {
        $this->inputmask($this->options);

        $this->prepend('<i class="fa fa-phone fa-fw"></i>')
            ->defaultAttribute('style', 'width: 150px');

        return parent::render();

The expression parent::render(); of type string|Illuminate\View\View|Illuminate\Contracts\View\Factory adds the type Illuminate\Contracts\View\Factory to the return on line 27 which is incompatible with the return type declared by the interface Illuminate\Contracts\Support\Renderable::render of type string.
