Caused by ngControl.valueChanges not available when converting to signal

#suffixPrefixValue = toSignal(this.ngControl.valueChanges.pipe(startWith(1)));

value should be access after view init

ngAfterViewInit(): void {
  this.ngControl?.valueChanges
    ?.pipe(takeUntilDestroyed(this.#destroyRef), startWith(this.ngControl.value))
    .subscribe((value) => this.#suffixPrefixValue.set(value as number));
}
