Gemini Code Assist UI Stuck on Splash Screen in VS Code (Windows) - Bisect Confirms GCA as Cul

I'm experiencing a persistent issue with the Gemini Code Assist (GCA) extension in VS Code, where the splash screen with the spinner gets stuck indefinitely, and the chat UI never loads. I've performed extensive troubleshooting, including a full migration to the VS Code System Installer and utilizing the Extension Bisect feature, which points directly to GCA as the cause.

Problem Description: When I open VS Code, the Gemini Code Assist splash screen appears in its pane, displays a spinner, but never progresses. The Gemini chat functionality remains inaccessible.

My Environment:

  • Operating System: Windows Windows 10 Pro 24H2
  • VS Code Version: 1.101.0 (System Installer)
  • Gemini Code Assist Version: 2.37.0

Detailed Troubleshooting Steps & Outcomes (Chronological):

  1. Initial Problem: GCA stuck on splash screen after upgrading to latest beta.
  2. Network Issue (Resolved):
    • Initially encountered net::ERR_NAME_NOT_RESOLVED for <URL Removed by Staff>
    • Confirmed msecnd.net and subdomains failed global DNS propagation checks.
    • This issue was resolved after updating VS Code to the latest stable version (which might have updated internal CDN references or fixed a caching problem). The chat.json error is no longer present.
  3. File System Error (Resolved):
    • Logs showed ENOENT: no such file or directory for chat_checkpoint_files at C:\Users\Scott\AppData\Roaming\Code\User\globalStorage\google.geminicodeassist\chat_checkpoint_files.
    • This folder (google.geminicodeassist) did not exist.
    • Resolved by manually creating the full directory path C:\Users\Scott\AppData\Roaming\Code\User\globalStorage\google.geminicodeassist\chat_checkpoint_files. The ENOENT error is no longer present in logs.
  4. VS Code Installation Migration:
    • Performed a clean uninstallation of the VS Code User Installer version.
    • Manually deleted all associated user data folders (%APPDATA%\Code, %USERPROFILE%\.vscode\extensions, %LOCALAPPDATA%\cloud-code).
    • Restarted PC.
    • Installed VS Code 1.101.0 using the System Installer (running as administrator).
    • Reinstalled Gemini Code Assist 2.37.0.
