am I missing something, or something? I have changed a lot, Baidu has changed a lot, and it is all wrong to change it over and over again.

first of all, ComponentModule does not use BrowserModule, or IonicModule.forRoot (). Second, import ComponentModule in APPModule is fine, and there is no need to introduce it in provider.
modify as follows:

  import { CommonModule } from '@angular/common';
  ...
  import:[CommonModule]
  ...
  
  export class ComponentModule
    import { ComponentModule } from '.....';
    ...
    import:[ComponentModule]
    ...
    
    export class AppModule
    import { ComponentModule } from '.....';
    ...
    import:[ComponentModule]
    ...
    
    export class Pay..Module
