Code snippet that reproduces the problem

Expected

// TestEnum.php
namespace App\Shared;

enum TestEnum: string
{
    use EnumHasValues;

    case Test1 = 'test1';
    case Test2 = 'test2';
}

// EnumHasValues.php
namespace App\Shared;

trait EnumHasValues
{
    public static function toValues(): array
    {
        return array_map(
            static fn ($enum) => $enum->value,
            static::cases()
        );
    }
}

Actual

namespace App\Shared;

enum TestEnum: string
{
    case Test1 = 'test1';
    case Test2 = 'test2';
}
