Bug Description

Description:
When disabling WorldGuard on my Minecraft server, an error occurs. The error log points to an IllegalStateException: zip file closed related to the PluginClassLoader and a ProtectionStones interaction. Below is the full error log for reference.

Steps to Reproduce:

Run a server using Purpur version 1.21 with the following plugins:
WorldGuard v7.0.12
ProtectionStones v2.10.5
Disable the WorldGuard plugin while the server is running.
Observe the error during the disabling process.
Expected behavior:
WorldGuard should disable cleanly without throwing any exceptions.
