Hey, this is a known issue. It’s a bug in Plan mode in version 2.4.21 that can cause the window to freeze and crash.

Good news: the team has already fixed it. The fix should ship in the next update. Similar reports: Window crashed when model generate plan with plan mode

Workaround until the fix lands:

  • Use Ask or Agent mode instead of Plan mode. The issue doesn’t trigger there.
