Reporting a problem with the Gemini Code Assist plugin for Visual Studio Code v.2.30.3.

When loading the plugin, the side bar for the plugin has the clock loading icon and never loads. and I had to go to the command palette > Developer : Show Logs > Extension Host > then I filter by "google" and find the following error logs:

2025-04-08 16:49:52.738 [info] ExtensionService#_doActivateExtension google.geminicodeassist, startup: false, activationEvent: 'onStartupFinished'

Steps Taken:

NVM and Node.js have been uninstalled, and shell configuration cleaned.
The issue occurs even without a workspace loaded, and with a minimal VS Code setup.
