Server refusing to start

Question

I closed my server like I've done tens of times by doing /stop, and then starting it via the dashboard. Now the servers refuses to start and this is the crash log. I've tried putting in /gamerule randomTickSpeed 0 - 5 multiple times on startup, but it doens't work. I've tried repairing the files and restoring the server from a savefile, and it doesn't work. There is literally no reason that this started happening.

I've done that several times, to no avail.

Go to your file manager (don't go into any folders) and delete all files ending with ".json" and then try starting your server.


I'm just a known player who been playing since the 24 July 2019.

Please don't DM me for support, go here (if you don't mind waiting) or join Minehut's Discord (which is more active) if you need assistance.
