Expression has changed after it was checked. Previous value: ‘ng-valid: true’. Current value: ‘ng-valid: false’

I faced the same issue and I fixed it by using AfterViewChecked and ChangeDetectorRef:

import { AfterViewChecked, ChangeDetectorRef } from '@angular/core'

export class ClassName implements AfterViewChecked {
  constructor(private readonly changeDetectorRef: ChangeDetectorRef) {}

  ngAfterViewChecked(): void {
    this.changeDetectorRef.detectChanges();
  }
}
