Ng serve is working but ionic serve is failing - node.js

Question

I'm building an app using Ionic 6.19.0 and it suddenly started to face building issues.
I get Error: spawn UNKNOWN each time I execute ionic serve.
This is my package.json file

Here are few solutions that might help:
Ensure you're in the root folder of your project.
Try fixing the existing node_modules folder with npm rebuild + reassign
permissions to your node_modules folder: chmod 755 -R
/path/to/node_modules
Remove node_modules and reinstall with npm install
