Hey, thanks for the report.

This looks like an extension-related crash. We’ve seen similar issues with other exit codes. Try this workaround:

1. Close Cursor
2. Run this in Terminal: cursor --disable-extensions
3. Try the same agent prompt

If it works without extensions, then one of them is conflicting.

To find the problematic one:

• CMD + Shift + P → “Developer: Open Extension Monitor” (first enable it in Settings → Application → Experimental → Extension Monitor Enabled)
• Or CMD + Shift + P → “Developer: Open Process Explorer” and check the extensionHost process

Can you share:

• Which extensions you have installed
• Whether it reproduces without extensions
• The exact prompt that triggers the crash (if it still crashes without extensions)

Let me know how it goes.

Hey, it seems that extensions have nothing to do with such crashes.

I removed all extensions, but Cursor still crashes regularly.
