What's Wrong?

When I was writing a prompt to exceute in the claude extension inside VS code terminal Subprocess initialization did not complete within 60000ms this error is showing, then I logged out of the claude code. Now while signing in again the same error is shown

What Should Happen?

Claude should have executed the prompt or after that should have signed it again on loggin out.
