What's Wrong?

Claude is not getting started from the Terminal ( tried Bash, PowerShell, and also a standalone Windows Terminal), and all the terminals have the same behaviour.
As suggested by Claude, I tried to figure out the issue, but was unsuccessful. Finally, Claude suggested that this is a bug with the Bun raw mode error, and mentioned it on a corporate Windows machine. This is a known class of issue.

The error that I got is mentioned below,
