Jupyter Notebook Freezing Cursor

Describe the Bug

The app performs much worse when Jupyter notebooks are loaded in. I cannot get it to generate any code in the side panel, and scrolling through the notebook, writing code, etc. is very buggy. I end up with the window freezing out.

“The window is not responding. You can reopen or close the window or keep waiting.”

I’ve seemed to localize this issue to Jupyter notebook (a cpp script runs fine with agent mode). I’ve also re-tried using both the universal and Arm64 versions.

Steps to Reproduce

Use jupyter notebook

Expected Behavior

code can be edited, responses can be generated
