H5P ''Embeded'' Activities ERROR

I'm having an H5P Error for embeded activities that I add on courses on MOODLE 5.2. The activities are open and functioning well. However, upon closing the platform, and clearing cash and relogging, I find some activities having the error showing in the screenshot below. Up to now, I have tried many codes etc... However, the error persists. I need a DEFINITIVE solution to this error so that it NEVER re-surfaces again. Please, ONLY contact me if you are SURE YOU CAN SOLVE THIS ISSUE. You have encountered it BEFORE.
