Hey, thanks for the report. This is a known issue in 2.4.x. Quite a few users are seeing hangs on “Planning Next Moves” and problems with terminal responses.
A couple things to try:
-
Roll back to 2.3.41 or 2.3.34. This is the most reliable workaround right now. A few users confirmed it fixes the issue. You can download it from Cursor · Download.
-
Run without extensions. From the command line, run
cursor --disable-extensions. One user fixed it this way, so it likely means one of the extensions is conflicting. -
Check indexing. Sometimes “Planning Next Moves” is blocked while the project is indexing. Make sure indexing has finished.
Also, can you confirm if this only happens with Opus 4.6 via BYOK, or does it also happen with Cursor default models? That’ll help narrow down whether the terminal hang is tied to the API key.
Let me know if any of these help.
