Hi @danhje, thank you for opening this issue and we're sorry that you're running into it!

I've also encountered issues with panels sometimes being empty while VS Code is being updated, and I see that you're on an older VS Code version (latest should now be 1.95.1 at time of writing). I would recommend installing the latest patch and reopening VS Code to see if it helps resolve the issue.

If this doesn't help, could you please share your console logs when the issue occurs? You can access that from the command palette (with ctrl+shift+P) and the following text:

It would be great if you could share any error messages you see in the console logs. Thanks!
