Since updating to 2.1.46 the agent can't update any files

Kevin_Roche · December 3, 2025, 3:46pm

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

When the agent makes changes to a file it fails to change anything.

It also tried to search the web for a solution but nothing happened.

Steps to Reproduce

Just get the agen to make a change and it doesn’t happen

Expected Behavior

Agent makes a change and the file is actually changed

Operating System

Windows 10/11

Current Cursor Version (Menu → About Cursor → Copy)

Version: 2.1.46 (user setup)
VSCode Version: 1.105.1
Commit: ab326d0767c02fb9847b342c43ea58275c4b1680
Date: 2025-12-02T03:59:29.283Z
Electron: 37.7.0
Chromium: 138.0.7204.251
Node.js: 22.20.0
V8: 13.8.258.32-electron.0
OS: Windows_NT x64 10.0.26100

Does this stop you from using Cursor

Yes - Cursor is unusable

Hey, thanks for the report. Looks like an issue in 2.1.46 - we’re seeing similar threads today about agent.

Need exact details:

Request IDs for operations where the agent “made changes” but the file didn’t update (Chat menu > Copy Request ID)
Screenshots of errors from Help > Toggle Developer Tools > Console during change application and web search attempts
Where the project is located: local disk/OneDrive/network path? Any antivirus/proxy/VPN?
Do git diffs appear or are there no changes at all?
Is this in all file types or specific ones (.yaml/.conf etc.)?

Quick checks:

Check which mode you’re in (Ask, Agent)
Settings > Network > Run Diagnostics; if anything’s red - send a screenshot
In Settings Ctrl+, search for “HTTP/2” and enable “Disable HTTP/2”, then restart Cursor
Run without extensions: cursor --disable-extensions and check
Test in a clean local folder (outside OneDrive/network drives) on a simple file
Compare: Do Inline Edit/Tab work but Agent doesn’t?

Hi Dean,

The issue happened for all requests yesterday but after I posted the message, I stopped and started Cursor. Then a couple of requests worked successfully, followed by another one that did not. So it is now intermittent. Some requests are able to update my files, others are not.

0a8a327b-5d20-48e4-b458-fe16f3677d03

There was a lot more after that.
The project is on my Windows 11 C: drive (Not OneDrive or a Network) It has worked perfectly for a couple of months.

During that time there were no changes at all. In the end the AI was suggesting That I make changes manually which was working. The agent could read my files but not write them.

The file types were CFML .cfc and .cfm files

I was in Agent Mode.

As you will see, I had an argument with the AI which insisted it had made changes bit I could see they had not been made in my editor. (I checked with another editor rather than Cursor)

At present, I don’t have the issue so I am not sure if Settings > Network > Run Diagnostics; would help but I cant find a settings menu.

I have Sophos Anti-Virus installed.

UPDATE

After posting the above I updated to version 2.1.47 and have not had any issues today.

I have found the Network link under File > Preferences > Cursor Settings > …

I also have this problem.
It just keeps loading infinitely. shell commands also dont work…

Im using WSL, i’ve also already uninstalled cursor and reinstalled it.

deanrie · December 4, 2025, 11:48am

Thanks for the additional details and request IDs.

Good news - it looks like this is a bug in version 2.1.46. You’ve already updated to 2.1.47 and the issue is gone, which matches other reports.

@j.v.z, you need to:

Update to 2.1.47 (Settings > About Cursor) and check if the problem is resolved
If bugs remain in WSL - share request IDs and screenshots from Developer Tools (Help > Toggle Developer Tools > Console)
Check Settings > Network > Run Diagnostics - any red flags?

Everyone else - if you still have issues with file updates in 2.1.47+, let me know. Otherwise, the issue is resolved!

Sometimes i get a requests approval notification?

j.v.z · December 4, 2025, 12:13pm

I just re-installed it as User and now it works after i press accept. but it’s asking for approvals every time. even when it’s in agent mode. with every model.

Update: Nevermind it’s inconsistant sometimes it asks for an accept and actually saves. and sometimes it doesnt do anything.
