The agent execution provider did not respond within 4 seconds. This may indicate the extension host is not running or is unresponsive

Eternal_Garden · January 14, 2026, 12:40am

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

Opened cursor project ive been working on this week and first thing i get is this:

“The agent execution provider did not respond within 4 seconds. This may indicate the extension host is not running or is unresponsive.”

I was able to open a different project and push an update, so it seems it could be specific to this project.

Steps to Reproduce

Put in any request to push a new update/change.

Expected Behavior

Should be pushing a simple design change, but instead i get this error.

Screenshots / Screen Recordings

Operating System

MacOS

Current Cursor Version (Menu → About Cursor → Copy)

Version: 2.3.34 (Universal)

Does this stop you from using Cursor

Yes - Cursor is unusable

Hey, thanks for the report.

This is a known issue. It’s most often related to Git not being installed. Agent mode needs Git to work. Please try this:

Check if Git is installed: open Terminal and run git --version
If Git isn’t installed, install it from Redirecting…
After installing, fully restart Cursor
Try using Agent again

If Git is already installed but the issue is still there:

CMD+Shift+P → “Developer: Reload Window”
Check Extension Monitor: Settings > Application > Experimental > Extension Monitor Enabled, then CMD+Shift+P → “Developer: Open Extension Monitor” and see if any extensions look problematic
Try running cursor --disable-extensions from Terminal. This will show if the issue is extension-related

You can also send:

Logs from Help > Toggle Developer Tools > Console, if there are any red errors

More details in a similar thread: Stuck with timeouts?

Eternal_Garden · January 14, 2026, 10:36pm

Hey thanks, I tried all of this:

Git is in fact installed
Everything runs perfectly in my other projects, just tested it out
Ran Cursor without extensions and still got the same error, cant seem to run anything in this project

Eternal_Garden · January 14, 2026, 10:39pm

Also - theres an error that pops up in the left hand side that reads “Extension Host terminated 3 times within the last 5 minutes”

deanrie · January 16, 2026, 4:22am

I see the standard steps didn’t help.

A couple of things I noticed from your logs:

The Extension Host is crashing with code 6
The path in the errors shows /Volumes/Cursor Installer/. It looks like Cursor is being run directly from the DMG, not installed. If so, drag Cursor.app into the Applications folder and launch it from there.

If Cursor is already installed properly, try clearing the workspace data for this project:

Fully quit Cursor
Open ~/Library/Application Support/Cursor/User/workspaceStorage
Delete the folders related to the problematic project (or delete them all, they’ll be recreated). Make a backup first
Restart Cursor

A couple more questions:

How big is the project (rough file count, and do you have large node_modules or a .git folder)?
Is this a new project, or have you worked on it before without issues?

This is a known Extension Host issue, and the team is working on a fix.

gongmin · January 16, 2026, 6:16am

I tried all the steps but none worked!

gongmin · January 16, 2026, 6:18am

same here,disabled all the extensions but still didn’t work.
