PEX crashing?

[xMattRA]

Hi there!

So I installed PEX version 1.23.3 on my server and it was all good but then I restarted my server and it just stopped working. No commands worked. It didn't come up in /? or /pl.
Here is my console log.

Here is the Spigot version I am using.

Are you able to help me at all?

Go over here and get PEX 1.23.4 for your server.

Stop the server, install this .jar file, delete the old 1.23.3 .jar file, start the server, and see if you get the same error.
