'Broken pipe' error message in log file and crush on macOS

[anzhi0708]

Summary

I have experienced over 10 crashes during last 2 days on macOS 12.3. The issue is most likely with language server. After Async job failed error message appeared inside the editor, language server stoped working and if I try to quit the editor, the whole terminal freezes for 15 seconds then crashes.
During the 15 seconds' freeze, keyboard input seemed to be recorded.

I've set $RUST_BACKTRACE to full, but when this error occurs, console shows NO backtrace information. I was trying to edit a objective-c source file. I remember similar crash last year when I was editing a python file with pylsp set up. Same warning ('Async job failed: content modified') appears on Termux too.

Reproduction Steps

I'm not sure what caused this error. I was using an English keyboard layout. Even though I have Korean & Simplified Chinese input method set up on my system, I was not using them. But I do have some screenshots here...

I am closing thus as stale since the helix version this was reported against is ancient. This was likely fixed already (quite likely the code that chased this doesn't even exist anymore)
