Looks like watchdog killed your server - maybe one of your plugins causes lags
Go to server.properties and set
max-tick-time to -1
This will disable watchdog and prevents this kind of crash
Did you use worldedit (copy-paste-work) before that crash?
If not then it is maybe an issue with a discord related plugin or votifer
For future issues use paste.ubuntu.com to share your crash-logs
