Server keeps crashing when starting up

[PumpkinBrake221]

Every time myself or someone else tries to start up my minehut server, it appears to start up and then immediately go offline. I cannot figure out what is causing the issue, but I'd really like to be able to access my server again... this has been happening for a few days now so I know minehut is not simply at max capacity. Here is the crash report and thank you so much for any help!

 

EDIT: This was fixed by changing my gamemode and difficulty settings to something else and then back to what they originally were.
