Cursor froze & leaked memory during plan mode with Opus 4.5

[Colin]

Thanks for reporting this @jpark!

We’ve had a few reports like this on Plan Mode, and a fix is coming.

Window crashed when model generate plan with plan mode

Thanks for the detailed logs. I’ve shared the infinite loop bug in metrics collection with the team. It’s a regression in 2.4.x. Right now there’s only one workaround: use Ask or Agent mode instead of Plan mode. The issue doesn’t trigger there. As soon as there’s a fix, we’ll update the thread. Sorry for the inconvenience. Plan mode is indeed broken in your case.
