Hey, thanks for the detailed report and the Request ID.
Confirmed, there are infra issues right now affecting Composer 2 and Auto mode. It’s not on your side, this is impacting many users.
Until things stabilize, you can try a workaround: manually pick a specific model like Claude Opus 4.6 or another one instead of Auto or Composer 2. A few users in this thread confirmed it unblocked them: Taking longer than expected on Cursor version 3.0.13 - #22 by Garrett_Giles
The team is aware. Let me know if the workaround helps.
