Describe the Bug

When I am trying to install the cursor to connect from the macOS app, I downloaded the file from v6. And when I tried to install using the cursor macOS app, UI is instantly crashing the moment I type exten. And after trying several times by restarting the app, it was successful. When I tried to execute the code, there were some errors in the terminal. And when I tried to use the copilot features and everything by side, you know like the UI is instantly crashing. And I don’t know what to do here despite trying it open multiple times. But there are so many serious issues with the UI. I am not sure why. So, can you please able to help me here.

Steps to Reproduce

I tried to close the application and reopen the application multiple times because of the UI issues, and even though in the new update, the issue hadn’t been fixed.
