Cursor IDE
On every agent run no matter where it is a primary or subagent, cursor will silently pause on any action (most often a GREP or file search). Even after total application restart, it fall back to the same issue. I have attempted with both Claude Opus 4.6 and Gemini 3.1 pro and both attempts experienced the same behavior. Currently Cursor is unusable.
Open up an agent, enter a prompt and wait for it to silently pause.
The expected behavior is that when I run an agent or a subagent that it will go through the steps and complete the task.
Windows 10/11
Version: 3.2.11 (user setup)
Claude Opus 4.6 and Gemini 3.1 pro
N/A
Yes - Cursor is unusable

Hey, thanks for the detailed report. This matches a known cluster of freezes in 3.2.x during agent runs, often triggered by grep or file search, and we’re tracking it on our side. The same pattern is discussed here: Agents freeze at grepping and subagents and here: Sub Agents wont run and are stuck at "New Subagent - Starting up" . I can’t share an ETA for a fix yet, but I’ll link your report to our internal issue.
To help with diagnostics, can you please send:
A Request ID from one of the stuck runs. Go to Cursor Settings > Privacy, turn off Privacy Mode, rerun it, then in the chat menu top right three dots > Copy Request ID.
Process Explorer during the freeze: press Ctrl+Shift+P, run Developer: Open Process Explorer. Please take a screenshot while it’s paused, we’re interested in what’s using CPU and RAM, especially extensionHost and ptyHost.
Whether it still freezes if you start Cursor without extensions: from a terminal run cursor --disable-extensions.
Also please check if there are any errors in Output View > Output > Cursor at the time of the freeze. If yes, send the log.

After running with developer tools and disabled extensions, I simply running an ASK mode request where it spun up a subagent, it froze and I captured this on the console. Please keep in mind privacy mode is a requirement as I am running on a corporate environment.

Thanks, the log helped. The OTLPExporterError: "Trace spans collection is not enabled for this user" noise is telemetry the server rejects because of Privacy Mode, it is not the cause of the freeze. Please keep Privacy Mode as it is, I get that it is a corporate requirement.
The useful signal in your log is this line:
[agent_exec] [watchdog, LocalReadExecutor] permissionsService.shouldBlockRead still not completed after 3000ms
So the freeze happens when the agent checks permission to read a file. That matches your report, the pause happens during GREP or file search. Also, later it says Extension host became UNRESPONSIVE. The fact that it reproduces with --disable-extensions is also helpful, we can rule out extensions.
To narrow it down, can you please answer:
Where is the workspace located, local disk, network share, UNC path (\\server\...), or a mounted network folder? In corporate setups this is often a factor.
Rough repo size (file count or GB)?
Does the project have a .cursorignore or a very large .gitignore?
If you open a small local test project (a couple files on C:) and run the agent with GREP there, does it also freeze or does it work fine?
I can’t give an ETA for a fix yet, but I’ll post an update in the thread as soon as I have one.
