What's Wrong?

Hi,

I can't find another report stating this issue that has been recent and not closed. Since mid july, it seems I have a bug in my IDE (Pycharm) when I use Claude in the terminal of the IDE.
The IDE keeps freezing at random times, and I am loosing everything I have been doing since the last backup as I have to force close the IDE. Even when I want to commit and push manually it's impossible when Claude is open (not even in use).

What Should Happen?

Normally, I should use the IDE and Claude without any interruption and smoothly (like it was before july). The screen is not supposed to freeze or crash every few minutes when I use it.

Steps to Reproduce

  1. Open Pycharm and any project you're working on
  2. Open the terminal and use claude in here
  3. Ask him to help you work on your project
  4. At some point, the IDE will crash

I do not have precise information as the crash is mainly happening when I am discussing with Claude.
