What's Wrong?

claude code version: v2.1.81
When using the CLI tool to execute tasks, it gets stuck during native tool invocations. Currently, I've noticed that it sometimes hangs on the bash tool and sometimes on the Read tool. I am very confident that this is not caused by network issues, because I have encountered this exact problem on different devices using the same account! This issue happens very often!

What Should Happen?

It should return an output properly. Even if the bash command fails, it should still output an error message or log, rather than hanging without a response for a long time!

Error Messages/Logs

After hanging for a long time, it throws an 'API ERROR'.

Steps to Reproduce

Please read all the source code in the project directory and help me generate project documentation.
