Hello @ATIQUE ABDULLAH ,
Welcome to Microsoft Q&A forum.
This document says,
VS Code doesn't have built-in support for HTML preview but there are extensions available in the VS Code Marketplace. Open the Extensions view (Ctrl+Shift+X) and search on 'live preview' or 'html preview' to see a list of available HTML preview extensions.
Therefore, you may have installed theses HTML preview extensions that may affect VS Code settings. Please try the followings:
1.Disable these extensions in VS Code.
2.Open HTML files with Text Editor.
Best Regards,
Dou
