What's Wrong?

When I upgraded Claude Code to version 2.0.1, I suddenly found that every time Claude Code needed to modify files using git and I accepted the modification, an Error would occur: File has been unexpectedly modified. Read it again before attempting to write it. I suspect that IDEA or some plugin in it modified the source file again before Claude Code was ready to modify the code, resulting in inconsistent calculation of the patch (diff/patch). I tried to uninstall and disable all installed plugins or restore the entire Settings, but the above-mentioned abnormal problem occurred. Now I can't use Claude Code in IDEA. I can only use the MCP Server and let Claude Code directly modify the file. This problem emerged only after I upgraded Claude Code.

I want to know if this issue is related to IDEA or some of its plugins. Right now, I'm completely unable to use IDEA to work properly。If you need more information, I can provide it at any time. Please let me know immediately. Thank you very much。

What Should Happen?

After I accept it, I should be able to modify the file successfully
