the selectedItems for p-autocomplete should not be of type string since it has multiple values. Therefore an array should be used. When you expand the code in the showcase it shows the correct way https://v18.primeng.org/autocomplete#multiple

    <p-autoComplete 
    formControlName="selectedItems" 
    [suggestions]="items" 
    (completeMethod)="search($event)" 
    [multiple]="true" />

new FormGroup({
    selectedItems: new FormControl([]),
})
