Julia for VS Code: error when trying to output plot

I get this error:

Error loading webview: Error: Could not register service workers: 
InvalidStateError:
Failed to register a ServiceWorker: The document is in an invalid state..

Here are the versions:
Julia1.63
julia for vscode : 1.4.3 and 1.5
VS code :1.62.2
On ubuntu 18

Thanks in advance
