Blocked by EasyPrivacy
Technically not an issue with Keypress.js, but nonetheless makes it harder to use:
EasyPrivacy (https://easylist.to/), which is a very common adblocking/content-blocking list, contains a filter that blocks any script named Keypress.js (/keypress.js$script). You can, of course, evade this by renaming the script to something else, but it might be worth reaching out to them to see if they are deliberately blocking your script (which would be strange, since it's just a library and doesn't do anything malicious on it's own) and if they could remove or tweak that filter.
Most likely it's just a common word that scam sites name keylogging scripts. I would suggest renaming this library in general, because it's very difficult to find help related to this library by typing in "keypress" or even "keypress.js" in google.
