Angular Material Dialog: dialogRef.afterClosed() subscription not triggered

Question

i am using material ui to open a component inside of a Mat-Dialog. When I close the dialog, my subscription to the dialogRef wont trigger.

The parentComponent calls the editCatering() to open the dialog.

parentComponent:

import { MatDialog } from '@angular/material/dialog';

export class BewirtungListTableComponent ...{
   
    constructor(..., public dialog: MatDialog,...) {}
    

editCatering(data){
        this.requestSub = this.guestService.getGuestsByCateringId(bewirtung.id).subscribe((guest: Guest[]) => {
            let dialogRef = this.dialog.open(BewirtungEditComponent, {
                data: {data, guest},
                disableClose: true,
                autoFocus: false 
            });

            dialogRef.afterClosed().subscribe(result=>{
                console.log("dialog closed")
                console.log(result)
            })
    };

Then the dialogComponent closes on the onSubmit() call;

...
import { MatDialog, MatDialogRef, MAT_DIALOG_DATA} from '@angular/material/dialog';
...

export class BewirtungEditComponent ...
constructor(@Inject(MAT_DIALOG_DATA) public data,..., public dialogRef: MatDialogRef<BewirtungEditComponent>){}

onSubmit() {
...
            this.updateSub = this.bewirtungService.updateCatering(cateringCreate).subscribe(
                (b: Bewirtung) => {
                    ...
                    this.dialogRef.close(b)
                },
                () => this.notificationService.error('Die Bewirtung konnte nicht geändert werden.')
            );
        }
        else {...}
    }

I checked the dialogRef in the states of the parentComponent and the dialogComponent: They have the same ID and after closing the dialogRef`s state changes to 2.

Any idea why the dialogRef.afterClosed().subscribe() doesnt do anything?

UPDATE

I also tested to move the afterClosed().subscription to the dialogComponent:

onSubmit() {
            ...
            this.updateSub = this.bewirtungService.updateCatering(cateringCreate).subscribe(
                (b: Bewirtung) => {
                    ...
                    this.dialogRef.close(b);
                    console.log(this.dialogRef)
                    this.dialogRef.afterClosed().subscribe(()=>console.log("after closed editComponent"))
                },
                () => this.notificationService.error('Die Bewirtung konnte nicht geändert werden.')
            );
        }

But even there i dont get anything.
