Where does the bug appear (feature/product)?
Cursor IDE
Describe the Bug
My cursor is broken after i recently updated.
the chat is stuck at “waiting for extension host”
I already tried disabling my extension with the “Extension Bisect” and manually one by one even without any extension at all but still get same error. it has been unusable for like whole day for me
here was the last thing generated in the Log.

Steps to Reproduce
note: my cursor had a bug during failed update where my cursor is placed inside the " Local / Programs / cursor / - " folder, so i moved it back to the parent folder which is cursor. i did this because the - folder broke my “@browser” function. and it still broken event after this, so i had to tell the ai agent to fix itself, the browser work now but the button still doesn’t appear on my chat anymore.
Steps to Reproduce
1.Open the Cursor editor with multiple extensions there was like 6 in this are active.
2.i attempt to trigger an AI Agent command by typing stufff in the chat then press enter.
3.i wait for few second until it said the extension host to become unresponsive and crash.
4.then error notifications pop up: “Extension host terminated unexpectedly” followed by “Agent Execution Timed Out”.
Expected Behavior
The Extension Host should remain stable and handle multiple active extensions without crashing.
The AI Agent should receive a response from the provider within the 30-second execution limit after i disable every of the extension..
The editor should provide specific details on which extension caused the termination rather than requiring a manual Extension Bisect to find which extension is problematic,
