What's Wrong?

So, I have extension installed, was using it just fine, everything worked how it should. Then I temorary disabled it. Now, I enabled it again, and everytime I try to promt anything it sends me to login window. After I login (tried both using opening window in browser and authorization code), it opens chat window. But as soon as I promt something it sends me to login window again.

I'm using Windows 11, I tried re-installing extension, re-logging manualy, completly deleting files in User/.vscode/extensions and it all didn't work.

What Should Happen?

It should let me use it
