Moodle in English: Unable to set up development environment

Good day

I hope this is the right place for this problem.

I am trying to set up my development environment for the Moodle mobile app. I am making use of windows for development and I followed all the steps in https://docs.moodle.org/dev/Setting_up_your_development_environment_for_Moodle_Mobile_2

I am able to produce a working Ionic serve in my browser, by making use of ionic serve --lab

I am however unable to build an apk with ionic cordova build OR with cordova clean followed by cordova prepare, followed by cordova build android --debug

I have not made any changes to the source, merely made a fork of the repo and cloned it. I have also uninstalled all components needed for the development environment multiple times and tried the setup on several machines with all of them causing the same problems.

I receive the following errors when using cordova build android --debug

cordova build android --debug
