Hi,
It seems to be a common issue of yarn not executing postinstall scripts
yarnpkg/yarn#5476

I had this issue on a codespace environment, but not on my computer.
And it seems not happening on Github actions

You can manually trigger the post install script by executing

cd vscode
node build/npm/postinstall.js

Sorry, it might just be a problem with my computer
The directory ./sample provides a good example
I prefer to use "Felx-B/vscode-web/sample" over the bulky VSCODE
