Does this stop you from using Cursor

Yes - Cursor is unusable

Hey, thanks for the report. Glass code 5 crashes on nightly are a known issue that the team is tracking. Your info that traditional view works but Glass crashes within 30 seconds is helpful.

A couple of questions to narrow it down:

  1. What are you doing in Glass right before the crash? Typing in the agent chat, scrolling, running an agent, or does it crash even if you just leave it idle?
  2. Can you grab the main.log from Help > Open Logs Folder right after a crash? The timestamps around the crash would help the investigation.

For now, using traditional view is the workaround until this is fixed. I’ve flagged this with the team. No ETA, but your report helps with prioritization.

Thank you.

First time I opened yesterday it was fine and I was editing some rules then crash happened. I restarted cursor few times and also reloaded window. Since then it’ll just crash even if I don’t do anything.

Unfortunately will be away from laptop for a while but will share log later if it’s persistent.

Best,
Casper
