Branching Scenario not installing

Hi I am getting the following error when trying to install the Branching Scenario content type. On install from the hub, it just spins. On install from uploaded h5p package, it spins until php times out (max execution time set to 300). Other content types (e.g., multiple choice) install without problems. Does the content type require additional configuration?

I am using: wordpress 5.7.2 | h5p 1.15.3 | php 8.0.3 | apache 2.4.46

PHP Fatal error: Maximum execution time of 300 seconds exceeded in -----/wp-content/plugins/h5p/h5p-php-library/h5p.classes.php on line 909
