Async tests fail due to timeout

We are using jest 27 for our project in Angular 12 for running our unit tests. Locally, these tests run correctly but runnig them in a cloud agent pipe they break, appearing this error:

thrown: "Exceeded timeout of 5000 ms for a hook. Use jest.setTimeout(newTimeout) to increase the timeout value, if this is a long-running test."

This is the part of code that breaks:

const createHost = createHostFactory({
component: Component,    
imports: [
  TranslateModule.forRoot(),
  GridModule,
  MaterialWrapperTestingModule,
  ReactiveFormsModule,
  TooltipModule,
  TableEditionToolbarModule,
],
providers: [
  { provide: ContactsService, useValue: contactsServiceSpy },
  { provide: CustomerService, useValue: customerServiceSpy },
  { provide: CustomerDetailFacade, useValue: customerFacadeSpy },
  { provide: HeaderMenuFacade, useValue: headerMenuFacadeSpy },
  { provide: ContextFacade, useValue: contextFacadeSpy },
  { provide: MatDialog, useValue: dialogMock },
],});

 beforeEach(() => {
  host = createHost('<component-selector></component-selector>', { detectChanges: true, 
  props: { structure } });
  return host.fixture.whenStable();
 }); 

It takes too much time to run the tests and the task fails.

We have done several changes in order to solve it, but nothing helps:

• We have use already jest.setTimeout(newTimeout)
• We have alse used --runInBand to run tests serially
