Your Cordova tooling seems to be out of date, which might be causing all kinds of problems.
You can read about how to figure out the current Cordova versions and how to update CLI, platforms and plugins here: https://ionic.zone/cordova/update

This also doesn’t make sense. What does ionic cordova platform list return?
