Build in “prod” mode: Cannot find module “.” - Typescript version >3

Ionic Framework
1

Hi, I have updated my ionic project and all dependencies and now when I try to build a --prod android apk I get the following error:

Uncaught Error: Cannot find module "."
    at vendor.js:1
    at vendor.js:1
    at Object.<anonymous> (vendor.js:1)
    at e (vendor.js:1)
    at Object.<anonymous> (main.js:1)
    at e (vendor.js:1)
    at window.webpackJsonp (vendor.js:1)
    at main.js:1
vendor.js:1 Ionic Native: deviceready event fired after 57 ms
assets/icon/favicon.ico:1 Failed to load resource: net::ERR_FILE_NOT_FOUND

I’ve searched and googled so much and the Problem seems to be the typescript version (>3)
But all post are very old (2018) and the only solution was to downgrade Typescript to version 2.6
but this is not a solution for me because I have to use angular >= 7 for Firebase.

Is there a proper solution how I can get this to work???
