Somehow all my User settings in VS Code have been reset and deleted and when I open the user settings JSON file I cannot find my previous settings.
How can I restore my previous versions of VS Code settings?
Check out Settings Sync for Visual Studio Code. Under restoring data, you should be able to restore previous versions of your VSCode settings.
In addition, Settings Sync: Show Synced Data from the command palette allows easy viewing of remote and local backups of your preferences.
Note: Builds of Stable & Insiders pull from different Settings Sync services, occasionally leading to data compatibility issues.
