Run npm i --no-optional && cd client && npm i --no-optional && cd ..
npm WARN read-shrinkwrap This version of npm is compatible with lockfileVersion@1, but package-lock.json was generated for lockfileVersion@2. I'll try to do my best with it!

    }

i tried adding no-optional argument while npm i. and adding fsevent to optional dependencies. still causing same error.

Solution

I have something similar and is caused by nodemon. Had to revert to nodemon v1.19.4
