  2. build the extension (npm i)
  3. start the debug configuration run extension
  4. the development host should start

研究方向
Investigate the service worker registration in Electron's main process when loading webviews. The error 'The document is in an invalid state' suggests the webview content is not in a valid state for service worker registration. Compare with the webview sample from vscode extension samples to see how it handles service workers. Check the plugin host startup code in theia/packages/plugin ext/src/hosted/browser/plugin host.ts or similar. Also review any recent changes to the webview implementation.
