I am getting “Agent Execution Timed Out” repeatedly since yesterday. Tried resetting/deleting the cache; complete reinstall, disabling plugins still its throwing the same error. Even tried making a new simple “Hello World” project and agent is still throwing the error. I have worked with IT to disable all firewall and endpoint on my system but still it’s there.Anyone has any idea what I am doing wrong. It was working fine before.
Error Log:

Hi Rahul!
This is a known bug with the extension host initialization. Our engineering team is actively working on a fix.
I can see from your video that you’re using the Agents Window. There’s a specific variant of this issue where Glass silently blocks the agent from activating when a workspace isn’t trusted, and the setting can reset between sessions.
A few things to try:
Open Cursor from the terminal in classic mode: Run cursor --classic from your terminal. This should surface the workspace trust prompt properly. Trust the folder, then switch back to Agents Window and try again.
Restart the Extension Host directly: If you can get the command palette open (Cmd+Shift+P), search for Developer: Restart Extension Host and run it.
Export logs for our engineering team: Go to Help > Export Logs, save the zip file, and share it here. This will help our team narrow down the exact cause for your machine.
Also, could you share your Cursor version? You can find it under Cursor > About Cursor. This helps us check whether your version includes recent fixes.
@Shekhu - since you’re on Windows, your issue likely has a different root cause. Could you create a separate thread with your error details? That way our team can investigate your specific setup properly.
Thanks, though my issue got resolved with Ctrl + Shift + P → Developer: Reload Window. However, it still happens some time. I just reload the window and it gets fixed.
