Angular Datepicker invalid for no reason

I have an angular form in which there's a required date picker with [min]="now", it's always invalid whatever the date is.

I have two components that have this exact same form, for which I compared the code line by line and there is no difference. One of them is working perfectly while the other one doesn't work for some reason.

component.ts

<div [class.entry]="!form.get('acceptDate').value">
          <mat-checkbox class="checkbox" formControlName="acceptDate"
            ><strong>I accept the date range</strong> -
            {{ enquiry?.timeFrame?.earliest.toDate() | date }} -
            {{ enquiry?.timeFrame?.latest.toDate() | date }}
          </mat-checkbox>
          <br />
          <br />
          <mat-form-field *ngIf="!form.get('acceptDate').value">
            <input
              matInput
              [matDatepicker]="optDate"
              placeholder="Preferred date"
              formControlName="optDate"
              [min]="now"
              required
            />
            <mat-datepicker-toggle
              matSuffix
              [for]="optDate"
            ></mat-datepicker-toggle>
            <mat-datepicker #optDate></mat-datepicker>
          </mat-form-field>
        </div>

  now = new Date().toISOString();

  form = this.fb.group({
    acceptDate: [true, Validators.required],
    optDate: [null],
    acceptTaC: [true, Validators.required],
  });

If I remove the [min]="now", it will work.

You have 1 field (optDate) that is depending on an other (acceptDate). You should make optDate disabled if you don't need it, because acceptDate is true. Or make it enabled if acceptDate is false. And optDate also should have Validators.required validator, because if acceptDate is false, then the user should add an optDate. Right?

By the way, don't you forget to put all this into a <form [formGroup]="form">?
