Hey, thanks for the report. The OOM error code -536870904 has already been reported by other users. Let’s try to figure it out:

First, test Cursor without extensions. Run this in your terminal:
cursor --disable-extensions

If it works like this, then one of your extensions is causing the issue.

If the problem remains, please share:

  1. Does this happen only in this project, or also in a new empty folder?
  2. Which extensions do you have installed? (check in Settings)
  3. Do you have any MCP servers configured?
  4. Can you open Help > About Cursor and share your full version info?

Related workarounds from other users:

  • Clear workspace storage (project-specific):
    Close Cursor → Go to %APPDATA%\Cursor\User\workspaceStorage → Delete the folder that matches your project → Open Cursor again

Let me know what you find in safe mode!

It didn’t work… I switched to VS Code with Copilot, and it was the best decision I could have made.

Where does the bug appear (feature/product)?

I have the same issue…

Without very much to go on, i.e. “Vibe trouble shooting” ;-P, I see that my “cloud agent” is now synched into the Cursor IDE, and I think this may be related?

Looked in the logs and here is the “main.log”:

SOLUTION for me: Removed AppData/Cursor directory. Note - you loose a lot doing this…

Just got the same failure.

When the app reopens, after I type about 3 characters in the agent window it fails. I tried clearing the cache and still fails.
