Do you use any performance-enhancing mods (e.g. OptiFine) or custom server distributions (e.g. SpongeForge or Arclight)?

No response

Please provide the full logs. You can find the logs in the logs directory of the client or server. Most of the time latest.log is the correct file (unless the crash or issue happened during an earlier run).

Logs can be uploaded here by dragging the file into the comment field, or you can post them on a site like https://gist.github.com/ or https://pastebin.com/. Make sure they are set to be public (or unlisted) and to never expire.
