Angular 10 || 11 and Ionic 5: Generic type 'ModuleWithProviders<T>' requires 1 type argument(s) error

[almothafar]

Describe the bug
While building production app for ionic 5 with Angular 10 or 11 I get an error with Generic type 'ModuleWithProviders<T>' requires 1 type argument(s) error

To Reproduce
Just upgrade your app to Angular 10 or above (which is used in Ionic 5).

Screenshots

Desktop (please complete the following information):

• OS: Windows 10 Pro 64-bit & Ubuntu 20.4
• Browser does not matter as it is build process
• Version ^7.0.8

Additional context
The component working fine in Ionic 5 actually with latest angular (version 11), and I can workaround this issue by adding the following code to app.module.ts:

declare module '@angular/core' {
	interface ModuleWithProviders<T = any> {
		ngModule: Type<T>;
		providers?: Provider[];
	}
}
