You did not read the log at all

If you read the log you'd know both these did not cause the problem

Could not pass event InventoryCloseEvent to ItemEdit

[Essentials] Task #88 for Essentials v2.17.0.0 generated an exception

Could not pass event InventoryCloseEvent to ItemEdit v2.1-Beta

the problem is with plugins because there are errors associated with them

This is not what caused the crash, still. I am clueless what it was, but it seems to have something to do with a Spigot bug, caused by WorldEdit, or a pure WorldEdit bug

it seems to me that ItemEdit is to blame since the last error before stopping the server was related to it you should change all the plugins for the desired version

and in General, the Analysis did not find a problem with worldedit

The problem with the items thing was too long before the actual crash, and it appeared quite closely after the worldedit command was executed. Also, codex doesn't have an AI, it can't detect everything right
