What's Wrong?

If I open Claude like in the following screenshot of an empty project:

<img width="2559" height="1410" alt="Image" src="https://github.com/user-attachments/assets/cc860349-ebe2-48d9-8df2-13612e5019f1" />

When I close VSCode and reopen again, I end up with a locked panel where Claude used to be open:

<img width="2559" height="1416" alt="Image" src="https://github.com/user-attachments/assets/c4509a35-ff7b-4006-b9b5-95c31a0bbc67" />

I've tried settings like this but it doesn't help.

"workbench.editor.autoLockGroups": {
    "workbench.editor.processExplorer": false,
    "workbench.editor.chatSession": false}

It's slightly annoying having to unlock/close the panel when I want to do something with that space - really I'd be fine if it just reopened Claude again.

What Should Happen?

Claude should either reopen again or not leave behind a locked panel.
