Crundee Craft Server suddenly says stopping

The modpack is Crundee Craft. I start the server and everything is fine. It starts loading, then says starting... and then suddenly says stopping, and it stops.
This is the crash log.

I have no idea what is happening, me and a friend use Skyfactory 3, which is much bigger, without a problem.
Thanks for the help.
