Hey, thanks for the report. This is a known issue and the team is working on a fix.

For diagnostics, please try:

  1. Check extensions:

    • Run from terminal: cursor --disable-extensions
    • If crashes stop, re-enable extensions one by one to find the culprit
    • CMD+Shift+P > Developer: Open Process Explorer - share a screenshot right before the crash

  2. Check MCP servers:

    • Settings > MCP - disable all servers (especially GitHub, Atlassian), then restart Cursor

  3. Network and proxy:

    • Settings > Network > Run Diagnostics
    • If you use VPN/corporate network/Zscaler: in settings CMD+, search for HTTP/2 and enable Disable HTTP/2

We need artifacts for engineers:

  • Help > Open Logs Folder > attach main.log
  • Errors from Help > Toggle Developer Tools > Console (screenshot during the crash)
  • Results of the test with cursor --disable-extensions

Send the results and logs, please. We’ll check them.

Possibly being dense here :slight_smile: sorry
Run from terminal: cursor --disable-extensions zsh: command not found: cursor
Settings > MCP - I dont see MCP
I have the main.log for you, but unable to upload here (doesn’t like .log files)

Disabled python (only extension). No MCPs. Network diagnostics seems normal.

Crashed a moment ago, I was AFK and the agent has completed/responded to my last prompt. (So the crash appears not be about agent interaction).

Same bug, same crashes. I’ve already disabled all extensions, but the crashes are still happening. It also says that Electron isn’t working (or something like that).

The crash report says “Error 5”

8

Crashing every 30 mins or so. Before 2.2.20 I have zero crashes (intensive usage)

9

following the crash - the first interaction with an Agend hangs. the second seems to work.

10

crash frequency is now 5 mins :confused:

11

tried a reboot - crashing continues

Thanks for the logs! I see the issue:

[error] CodeWindow: renderer process gone (reason: crashed, code: 5)
[warning] [BrowserViewMainService] Cannot execute JavaScript: browser view not created

This points to the Electron renderer, possibly related to the agent browser. Please try:

  1. Disable the agent browser (if you use it)
  • Avoid opening the agent browser panel
  1. Command line (optional) - to use cursor --disable-extensions, install the command first:
  • CMD+Shift+P > “Install ‘cursor’ command”
  1. Try without GPU
  • Launch from terminal: cursor --disable-gpu
  1. Developer Tools console (very helpful for the team)
  • Help > Toggle Developer Tools > Console
  • Wait for the next crash and capture a console screenshot

Let me know which step helps.

Dean Rie hi! Do you know if there’s going to be a patch or any fix soon? The issue is still there after the latest update. Cursor keeps crashing for me after I read long documents and work with them manually in the editor, especially with large .md files.

14

I see several crashes an hour still too.

15

I am using paid-as-you-go pricing, so this bug is actively costing my funds, and every crash I need to recover the flow. Please can you update? (do I need to speak to support?)

Hey, thanks for your patience. This is a known issue and the team is working on a fix.

Please try resetting your settings - it helped other users with the same error:

cd ~/Library/Application\ Support
mv Cursor CursorBackup

This will create a backup of your settings in CursorBackup and reset Cursor. Your projects and code will remain untouched.

This solution worked here:

Give it a try and let me know if the issue persists.

It works actually, thank you @deanrie
