Welcome to StackOverflow Minh Phan! Please take some time to read about what makes a good question.
I would advise checking that you have the requirements for this plugin installed before trying to run the Blockchain commands from with Visual Studio Code.
I was able to install and open the welcome page with the following versions:
- Visual Studio Code 1.52.1
- NPM 6.14.8
- Node.js 12.18.4
- Git 2.29.2.windows.3
If you already meet the prerequisites I would try uninstalling the plugin and then closing Visual Studio Code, then re-opening and attempting to install the plugin and run the command again. Failing this, you may get better help by raising in issue against the repository for the plugin on GitHub.
