The crash seems to come from a (transient?) network issue.

However, if your want to check and possibly fix your map, you can use my Region Scanner tool to do that.

First use the scan mode (—scan) to analyze your map, and then use the other options (—delete chunks, —kill entities, —unknown blocks&items removal, etc.) to fix other identified issues (assuming of course that it has something to do with your map).
