What's Wrong?

When trying to use Claude Ai in as a sidebar code editor I cannot login. The message " Failed to retrieve auth login keeps happening. No matter the number of restarts, different versions etc using windows os.

Currently using VSCode version: 1.109.5
Node.js: 22.21.1

What Should Happen?

Should just let me login, as it works on macbook computer.
