Description
The backpack plugin just does not work at all. It's just a player head and when you run the command nothing happens. I use minehut to host my server and ever since it became 1.16.4 it stopped working.

Steps to reproduce
Tried to open the backpack.

Expected behavior
Open the backpack

Other information (e.g. detailed explanation, related issues, suggestions how to fix, links for us to have context, screenshots, etc.)
It happened ever since my server updated to 1.16.4. Essentials doesn't even see it as a plugin anymore on the plugin list. The files however are still there.

Seems to occurring to me too

Should be fixed with this update.
