Cursor crashes 3.7.9

Describe the Bug

I can not work. It just crashes.

Sorry, for opening this new one, but it feels like crash is another issue.

The similar crash started to happened from here:

Steps to Reproduce

  1. Run Nightly Cursor

Expected Behavior

no crashes.

Operating System

MacOS

Version Information

see here: Nightly cursor should run nightly agents

3.7.9

Does this stop you from using Cursor

Yes - Cursor is unusable

It would be nice if Cursor will allow easily rollback to the previous version.

phew… downloading from cursornightly and reinstalling manually seems fixed the problem

It sees solarized theme and do not crash.

hm… though “Try a new window for parallel agents” button opens the window, which do not recognized by configurations and crashes… =(

ok, I suspect that cursor do not see a required configuration options and then crashes.

My proposition is to improve exception handling at that part of application.

Hi Eugen , glad the manual reinstall got you working again.

The second problem (the “new window for parallel agents” failing when it opens) is a known issue we’re already tracking. The Agents Window can fail to render if it opens before some of Cursor’s settings have finished loading in the background - which matches exactly what you saw (“it doesn’t recognize the configuration”). Your last point is spot on: this should degrade gracefully instead of crashing, and that’s precisely the fix our team has in progress. I don’t have a release date to share yet.

In the meantime, the quickest workaround is to reload that window after it opens: Command Palette (Cmd+Shift+P) → Developer: Reload Window (or just close and reopen the Agents Window). Once the app has fully warmed up the settings are cached, so the window renders normally - the same reason your reinstall/restart cleared the earlier startup crash.

If it still crashes every time even after a reload, grab the exact error text from the panel (there’s a “Copy error” button) and paste it here - that lets me confirm it’s the same issue and not a separate one.
