Solution 1:^[1]

For future references: here an explanation and how to fix it. I also needed to edit the angular.json to change the cordova builder.

Solution 2:^[2]

I kicked out the issue by using this solution.

run sudo npm install -g @ionic/cli@latest
to install latest ionic package and run
npm outdated
to get outdated packages.
run npm install package_name@latest --force (replace 'package_name' with the outdated package name) for every package shown in outdated package list
Ignore any warning during update.

TIP:Updating all the outdated packages saves you from app's low performance and improves security

Solution 3:^[3]

Try to install - npm install @ionic/cordova-builders

Then goto angular.json inside "ionic-cordova-build" and "ionic-cordova-serve" and replace

"builder": "@ionic/angular-toolkit:cordova-build"

with

"builder": "@ionic/cordova-builders:cordova-build",
