@ntotten the problem here is that even when setting the vscode setting ;

"prettier.prettierPath": ".vscode/pnpify/prettier/index.js"`

(As done automatically by following https://yarnpkg.com/advanced/editor-sdks )

It looks like the plugins still tries to load the version from package.json first instead of the explicitly configured path.

For now, you will have to set the prettier path. This is probably going to be a fairly large investment to fix due to how yarn2 has changed dependency resolution. I will try to look into it soon, but if somebody has expertise with yarn2 a PR would be welcome.
