Installation and server related problems

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

Any PHP errors:

PHP Fatal error: Uncaught TypeError: property_exists(): Argument #1 ($object_or_class) must be of type object|string, array given in /var/www/webroot/ROOT/wp-content/plugins/h5p/h5p-php-library/h5p.classes.php:4037

Casting the $group varialble on line 4037 of /wp-content/plugins/h5p/h5p-php-library/h5p.classes.php to an object seems to fix it:

if (! property_exists( (object) $group, $field->name)) {
