So I tried to install a new plugin in my (working) Ionic app, and that would be https://ionicframework.com/docs/native/firebase-dynamic-links/
I had an odd error, so I tried a few things and ultimately got back to where I was using a git reset to completely undo what have been done.
... But the error won't disappear.
I tried to upgrade Cordova and Ionic, to remove node_modules and npm install again, to remove and add back Android platform... nothing helps.

[ERROR] An error occurred while running subprocess cordova.
I really need help understanding what the hell happens and how I can get over it.
Okay, finally got it working. Removed plugins folder, walked my plugins list to remove unnecessary stuff, removed node_modules folder, removed Android platform, upgraded everything, reinstalled everything ( you can use ionic cordova prepare for plugins if you want, or if you removed Android platform, adding it back will fetch plugins anyway). Build.
