Livewire component has 'undefined variable' after updating Livewire?

I've setup a FormField as Livewire component in the a testing app using Filament 3 and Livewire 3:

Component:
<?php

namespace App\Forms\Components;

use Filament\Forms\Components\Field;

class RangeSlider extends Field
{
    protected string $view = 'forms.components.range-slider';

    public string $testVar = 'testValue';
}


View:
<x-dynamic-component
    :component="$getFieldWrapperView()"
    :field="$field"
>
    Value is: {{  $testVar  }}

    <div x-data="{ state: $wire.entangle('{{ $getStatePath() }}') }">
        <!-- Interact with the `state` property in Alpine.js -->
    </div>
</x-dynamic-component>


Now where it says 'value is' it correctly echoed the value of my $testVar, but after updating via Composer it now throws an error Undefined variable $testVar

Is there any way to mitigate this?

Composer:

composer update -W
