Cursor temporarily bricked after update

Bug Reports

Describe the Bug

I was in the middle of coding when I saw an update button and pressed it. At the time, the composer was in the middle of suggesting changes which I didn’t finish reviewing.

As soon as cursor restarted I got this error: The editor could not be opened due to an unexpected error: illegal state - RECURSIVELY instantiating service 'composerService'

If it makes any difference, I’m working on a dev container.

I tried restarting cursor, restarting the container, clearing and deleting all the open chat instances. Nothing helped, my cursor was effectively bricked. I couldn’t view any files in my workspace and the terminal was stuck loading with this text:

Running the initializeCommand from devcontainer.json...

[527 ms] Start: Run: /bin/sh -c mkdir -p /Users/asafm/.devcontainers/maven_cache

Thankfully it resolved itself after about 30 minutes, but for 30 minutes I couldn’t work at all. Please fix this.

The version and system info after the upgrade is:

Version: 1.1.3

V8: 13.2.152.41-electron.0
OS: Darwin arm64 24.5.0

Specifically, I was working with the Google Gemini 2.5 pro when this occurred.

Originally I thought I ran into this issue but then realized this was a new issue.

Steps to Reproduce

I can’t easily reproduce this, but I assume these would be the steps:

  1. Ask changes in chat and be mid edits (after they are suggested but not accepted or not fully accepted).
  2. Click the update button in the popup notifying that an update is ready/available.
  3. When cursor reopens, the error above appears.

I assume that working on git repo and/or dev container are not related to the root cause.

Expected Behavior

After cursor reopens following an update in the middle of composer edits, everything works and I can continue my work from were I was before the update.
