 * I don’t have access the shared item in your Google Drive, but as I’m getting 
   the exact same error now (while you have autoptimize disabled) I think it’s safe
   to say this is an issue with your theme you’ll need to look into?

 * I just had another quick look at your site’s homepage and (a) I don’t see the
   error anymore and (b) there is not reference to `popper` in the HTML source. 
   Or do you see the error on other pages on your site?
