Problem: Keepinventory is activated by EssentialsX

fixed by giving people -essentials.keepinv permissions, its default enabled for all

It's not given by default https://github.com/EssentialsX/Essentials/blob/2.x/Essentials/src/plugin.yml#L560

Your log indicates you don't have a permissions plugin, or at least not one we support.

LuckPerms and some other permissions plugins work properly and respect defaults meaning they don't give the keepinv permission by default. PEX 1.x is known to ignore the defaults and we can't provide any guarantee that it will work properly.
