I've also had this issue. From what I've seen in #9886 and other issues, the main solution provided by people is disabling the ESLint plugin by adding DISABLE_ESLINT=true in the .env file.

I haven't seen much improvement with this - what has really worked for me was adding craco with esbuild. You can find instructions on how to do that here. It has dropped my build time from ~10 minutes to just 1-2 minutes, and dev server startup has decreased from 10+ minutes to ~3-4 minutes.
