Happy you got deepseek to work, we had problems with it last week.
Honestly no idea on the qwen issue. I just looked up "qwen" in the cline repo and there is some talk about qwen models... but didn't find the error matching your error.
We've found that cline is a complex and inconsistent beast at times. But when it does work, it's very helpful. Sonnet3.5 is the most consistent, but it does get expensive.
