Hi, this bug is still persistent for me, even in the new updates.

Below is another example to push this issue again, also to indicate that this issue still persists on v2.1.117
It got to 22k tokens within a minute or two, then it hung there.

Bumping again, executing a plan. It shot up to 14k tokens quickly and then froze there again. Right now it is on medium effort.

Why on Earth did I resubscribe to Claude Code. Sigh. Whenever I sign up again, it's just a constant shitshow of debugging issues like this.
I need it for work, otherwise I'd be gone too.
Bump. Still on this issue, it hung at 23,4k tokens during thinking for 5 hours and 23 minutes now.
Got the same thing just now, hung at around 20k tokens for almost 8 minutes straight ...
Bump against closure
Anthropic does not care, and never will.
Closing for now — inactive for too long. Please open a new issue if this is still relevant.
