I encountered the following error after running npm i && nom start. Running yarn install and yarn start gave me the same result as well.

Hi,
Upgrade additional libraries. From what I can see there is a problem with postcss-safe-parser, maybe it's a sass dependency. For such actions I use the library https://marketplace.visualstudio.com/items?itemName=pflannery.vscode-versionlens
I'm not talking about React libraries, just the additional ones.
