Hello @Mayank Topiwala ,
Thank you for taking time to post this issue in Microsoft Q&A forum.
This issue should be related to specific language service in VS Code, see if this document: IntelliSense - Troubleshooting helps.
Besides, since Visual Studio Code(different from VS) is currently not supported in the Microsoft Q&A forums, the supported products are listed over here: https://learn.microsoft.com/en-us/answers/, you can post this issue here: Stack Overflow tagged Visual Studio Code or here: GitHub - Visual Studio Code.
Thanks for your understanding, have a great day.
Sincerely,
Tianyu
