VSCode Makie - Error loading webview: Error: Could not register service worker: InvalidStateError: Failed to register a ServiceWorker: The document is in an invalid state

In VSCode-Julia 1.127.2, when I try to view a Makie plot it says

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

and doesn’t show the plot.

Any ideas? I tried restarting VSCode.

Killing all vscode instances seems to do the trick.
