How to resolve this? Can the code be updated please or tell me what to do. I would really appreciate it.

Also ''npm start'' results in the following but I assume this happens since the ''npm install'' gave all those errors.

wipe out the node module folder, delete package-lock.json but leave the package.json.
Run npm install and npm update to update any older packages.
Run npm cache clear --force
Run npm install dotenv.

it worked for me
