SyntaxError: Invalid or unexpected token in node modules

1. tried removing node modules
2. tried cleaning the cache
3. tried installing again
Every time trying to run through npm or yarn i am getting this syntax error.
Sometimes it is unexpected number error, Invalid or unexpected token : and ,

Start by reproducing the install or run command through npm or yarn and inspect the attached error screenshot alongside the reported syntax errors. Identify the dependency or environment involved; the issue is resolved when the project installs and runs without the unexpected token or number errors.
