Cursor AI Fails to Save Simple Code Modifications - Persistent Errors Even with Direct Copy-Paste


Hi Cursor Team & Community,

I’m experiencing a significant decline in Cursor’s reliability over the past week, specifically when handling basic code modifications. Even for trivial tasks like copying existing code and adjusting save formats/logic, Cursor consistently throws unexpected errors. Here are the details:

Issue Description

  1. Task: Directly copying functional code (e.g., JSON/CSV processing scripts) and modifying I/O logic.
  2. Expected Behavior: Successful save/execution with adjusted paths/formats.
  3. Actual Behavior:
  • Random syntax errors in previously working code after minor changes
  • False “undefined variable” warnings
  • Crash when saving files (Error: ERR_IPC_CHANNEL_CLOSED)
  • AI suggestions becoming nonsensical (e.g., proposing non-existent_module.xyz())
