I've tried uninstalling it to install it again to start from scratch but it's not working. I used sudo snap remove code and sudo snap remove code --purge. But once I install it again everything is there, every extension. everything.

Clean uninstall# If you want to remove all user data after uninstalling VS Code, you can delete the user data folders Code and .vscode. This will return you to the state before you installed VS Code. This can also be used to reset all settings if you don't want to uninstall VS Code.

Linux - Delete $HOME/.config/Code and ~/.vscode.
