Need help! Is it possible to downgrade H5P version?

Hi all,

I'm using Moodle 3.3.4 with Fordsn theme and H5P plugin 1.20

Since i'm upgared H5P plugin from 1.17 to 1.20, i got the issues until now i can't fix it about Course Presentation or Interactive Video not loading properly as i have posted

May i ask for your advise, Is it posible if i want to downgrade back to H5P 1.17 without lost the data or exiting courses that have made by H5P plugin in the Moodle system?

Note:  Just think from my baby step, If i copy all the h5p folders including subfolder and files from the original H5P 1.17 library and replace directly into mod/hvp folder under moodle. Is this might help or will get more trouble?


Thank you in advance 

What should i do> anyone please advise.

Note: I can access to SQL database or PHP  mod/hvp libraries but need advise how to do?
