I think you need to change the version of Prettier in package.json (this should resolve the error: "Invalid version Error: Invalid version") and downgrade VS Code to get Prettier working. This solution worked for me.

But try downgrading VS Code first. Maybe this will be enough.

I followed this YouTube video to downgrade VS Code to version 1.87: https://www.youtube.com/watch?v=9dhQm-9IbHA

Here are the versions I have in package.json:

• prettier: ^2.8.8

on my local machine:

• node: v18.18.0
• npm: v10.7.0
