Error returning collection from tag

[rspenc29]

Bug description

I get an error when returning a collection containing an associative array from a tag. Declaring the same collection within a template works, and casting to an array from within the tag before returning also works.

How to reproduce

class MyTag extends Tags {
    public function index() {
        return collect(['a', 'b']); // works
        return collect(['a' => 'b']); // ErrorException: Undefined array key 0 in file [...]/vendor/laravel/framework/src/Illuminate/Collections/Collection.php on line 1780
        return collect(['a' => 'b'])->toArray(); // works
        return ['a' => 'b']; // works
    }
}

{{ $var = {my_tag} }}

Logs

// ErrorException: Undefined array key 0 in file [...]/vendor/laravel/framework/src/Illuminate/Collections/Collection.php on line 1780
