Installation and server related problems

Hi everyone!
I am using drupal 7.82 and h5p-7.x-1.51 for content-types development purposes. My PHP version is 7.4. My localhost is based on Docker and I can't update my content-type cache from h5p.org. I can ping h5p.org from docker container terminal, but when I try to pick content-type to create interactive video I see next errors.

The H5P WordPress plugin seems to conflict with PHP 8.1 and causes a fatal error when viewing rendered modules due to an array being passed to the property_exists() function.

Detailed steps to reproduce the bug:

• Install H5P WordPress plugin (v1.15.6) on a WP site running PHP 8.1
• Attempt to preview any H5P content by clicking the title of a module on the wp-admin page H5P > All H5P Content

Platform and version number:
WordPress 6.1.1

H5P plugin version:
1.15.6

Hi

I just installed the version 1.15.5 of H5P, on wordpress (v 6.1.1), and php version 7.4.

I am  trying to create a add a new content but it doesn't load the tools, and stay blank (see image)

Im using query monitor and doesn't show any error,

on php-error.log shows
