If it still isn't working in your region, it may be due to temporary ISP or network filtering of GitHub content domains. This has been reported by some users in India in the past. See: [Times of India](https://timesofindia.indiatimes.com/gadgets-news/github-content-domain-blocked-for-these-indian-users-reports/articleshow/96687992.cms).
If your PowerShell session is running in **Constrained Language Mode**, some scripts and commands may fail to execute. To check the current language mode, run:
```powershell
$ExecutionContext.SessionState.LanguageMode
```
If it returns `ConstrainedLanguage`, you may need to switch to `FullLanguage` mode or run the script in a session with administrative privileges. Be aware that some security policies may enforce Constrained Language Mode, especially in corporate or managed environments.
