Hello there,
After reviewing the logs given, this looks like a world issue meaning your world will need to be reset for your server to be playable.
To reset your world, go to your panel > file manager and then find folders with your world name, delete all folders that contain your world name and then restart your server.
Any more questions regarding this should be asked here within a month of this comment to avoid Necroposting (posting on 1 month or older threads) as per Minehut's rules.
