Windows 10 Build 1909 search bar returns nothing but just a black page

The search bar just failed (no result but just a black screen) after Windows 10 Build 1909 update.

Sigh... Windows is still windows.

To solve it, disable the Bing search in Windows:

1. regedit
2. Go to "HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Search"
3. Add DWORD "BingSearchEnabled", value = 0
4. Add DWORD "CortanaConsent", value = 0
5. Restart
