Hi @govind patel ,
Welcome to Microsoft Q&A!
You can navigate to File > Preferences > Settings > type “activity” in the Search bar > Appearance > Workbench > Side Bar: Location > change it to left in the dropdown list.
Or try to reset all settings of Visual Studio Code.
If it doesn’t work, please report it to the dedicated GitHub-vscode forum where you would get support for this product. Thanks for your understanding.
Sincerely,
Anna
