hi @adi0900 and welcome to Cursor Forum.

You mention this happens after installing Qwen CLI, though as we are not making that application we can not provide support for it. We are making Cursor IDE and Cursor CLI but as your error is not within our apps, and not an error message we show from our code, we would be unable to change their code.

Could you reach out to the Qwen team to have a look?
