[Bug] Extended thinking hangs indefinitely, consuming all tokens without returning results

Bug Description
There must be some issues here recently. I can use CC only for a few prompts. Some tasks could run normally, but then each recent session ended with freezing thinking for a long time without any result back, then all tokens were gone, hitting the session limit. I tried so hard to save the tokens by using Sonnet instead of Opus. I'm broke and on very limited budget. It's all gone. I can't work right now. I hadn't had this issue a few weeks ago. But this week, my CC got hit problem. There was a issue for sure. Please help me with this ASAP.

Session ID: 3ee7b5b7-5011-4a95-9512-c48169ff6abf

The evidence is the context usage in session was still only 46% from the session started. No way it would drain all my tokens.
