babel-preset-react-app dependency error - Yarn 3

See original GitHub issue

Describe the bug

When attempting to use create-react-app with yarn 3, running the scripts returns the following error

Error: [BABEL] src/index.tsx: babel-preset-react-app tried to access @babel/plugin-proposal-private-property-in-object, but it isn't declared in its dependencies; this makes the require call ambiguous and unsound.

Did you try recovering your dependencies?

Add to your .yarnrc.yml:

      "@babel/plugin-proposal-private-property-in-object": "*"
