“unexpected PHP debug” by Child Theme Configurator

Hi

I am trying to create a child theme of Kenta with Child Theme Configurator plugin. But it showed “unexpected PHP debug” with the following msg:

Deprecated: Return type of Illuminate\Container\Container::offsetExists($key) should either be compatible with ArrayAccess::offsetExists(mixed $offset): bool, or the #[\ReturnTypeWillChange] attribute should be used to temporarily suppress the notice in C:\Users\User\Local Sites\zigazzyfoodtest3\app\public\wp-content\themes\kenta\lotta-framework\vendor\illuminate\container\Container.php on line 1231

What’s wrong? How can I fix the bugs? Thanks.
