Class "Faker\Factory" not found

Hi I have double-checked my Laravel app with filament and there are only vendor files using the faker library I am not using it in my code, but Forge is showing this error:

In DatabaseServiceProvider.php line 93: Class "Faker\Factory" not found

I have seen some people say move faker to required in composer but I find it strange as I haven't used faker in my code, so do not need it in production, what can I do to fix the issue? thanks
