crash-2023-06-07_16.01.27-server.txt

I get the exact same error when generating chunks in the Nether (and no other time). Setting Chunky to pregen will usually cause this within a minute.

may it cause by offline account . the crash seems to disappear after i enable online-mode。

No！！！ After using online mode, I encountered this problem again today. This crash should be unrelated to offline accounts

I just encountered this exact same crash less than 2 minutes after entering the nether.
