Unable to find constructor for: H5P.InteractiveVideo 1.22


I'm trying to figure out why  a wordpress site isn't loading interactive videos. Any assistance would be appreaciated. As I'm relatively new to H5P I'm not sure if I uninstall the plugin will this remove all of the content. So I haven't tried that yet, I don't have a staging site to test on unfortunately. 

 Site is ngnix running on an AWS EC2, no cache enabled

  • Detailed steps to reproduce the bug (exactly how and when did it happen)

This has been broken for a few weeks, but there were no courses using this.

Upgraded Wordpress to 5.7 from 5.6.
