Runtime Error, Could not find cordova.js script tag. Plugin loading may fail

Ionic Framework
1

Hi all,
I added some plugin to my ionic5 app and after this my app not works.
I built for browser platform (test purpose) and for android.

It works successfully with “ionic serve” and if I test on my real device in debug mode.

If I built for browser latform or android for the store, it not works.

In browser platform I receive this errors and white page:

Could not find cordova.js script tag. Plugin loading may fail.

If I edit angular.json and set aot and buildOptimezer to false it works but for me it is not a good solution.

"configurations": {
            "production": {
              ...
              "aot": false,
              ...
              "buildOptimizer": false,
              ...
            }
          }
