已获VS Live Share私有Beta资格却无法使用及启动会话，求解决方案

Hey there, sorry to hear you're hitting this frustrating roadblock with the Live Share private beta—let's walk through some practical fixes that often resolve this "not admitted" error, even after logging out and back in:

• Verify your beta account association
  Double-check that the Microsoft account you're using to log into VS Code is exactly the one that was granted beta access. Head to the private beta management page tied to your account to confirm your status is marked as active. Sometimes invites get linked to a different account by mistake, which creates this access mismatch.

• Clear Live Share's local cache and storage
  Stale local data can prevent the extension from syncing your beta status correctly. Here's how to fix it:

  1. Fully close VS Code
  2. Navigate to the Live Share extension directory:
     • Windows: %USERPROFILE%\.vscode\extensions\ms-vsliveshare.vsliveshare-* (replace * with the installed version number)
     • Mac/Linux: ~/.vscode/extensions/ms-vsliveshare.vsliveshare-*/
  3. Delete the cache and storage folders inside this directory
  4. Restart VS Code and re-login to Live Share

• Reset Live Share user data via command palette
  Use VS Code's command palette (press Ctrl+Shift+P on Windows/Linux, Cmd+Shift+P on Mac) to run the Live Share: Reset User Data command. This wipes local authentication caches and forces the extension to re-fetch your beta eligibility from the server. After running it, restart VS Code and log back in.

• Update VS Code and Live Share extension
  Outdated versions of VS Code or the Live Share extension might have compatibility issues with the beta's access validation logic. Make sure you're running the latest stable build of VS Code, then go to the Extensions panel, search for "Live Share", and click the "Update" button if an update is available.

• Check your network environment
  Proxy servers or restrictive firewalls can block Live Share's communication with its authentication servers, leading to false "not admitted" messages. Try switching to a direct, non-proxy network temporarily, or disable your firewall briefly (just for testing—remember to re-enable it afterward) and see if the issue persists.

If none of these steps work, reaching out to the Live Share support team with your account details and a screenshot of the error message will help them dig deeper into your specific case.
