VS Code openHAB Extension!

Thats what i already said 20h ago and 1d ago.

But i have never heard of problems like this before.
From what you told here, you have installed the extension directly through the extension marketplace in the extension tab.

You could try to uninstall and install from a .vsix file.
You can find the current releases here: Releases · openhab/openhab-vscode · GitHub
