If you need more info please let me know.
After testing this, I can confirm that this error does not occur on a clean 1.13.2 spigot install with just EssentialsX installed.

As far as I can tell from your stacktrace, this error is caused by another plugin called Magic. It seems that Magic is not compatible with the current version of EssentialsX, as it is still attempting to use classes that have been removed in recent versions of EssentialsX.
You are probably correct. It looks like a compatibility issue due to some API changes. I just post the issue to MagicPlugin team. Waiting for response...
