Have you tried temporarily disabling focus trapping when using 3rd party libraries? https://ionicframework.com/docs/api/modal#focustrap

Ionic is trying to ensure focus remains inside of IonModal. It doesn't know that MUI's date picker also shows its own modal. To fix this, you'd want to disable focus trapping on IonModal when MUI's modal opens and re-enable it on IonModal when MUI's modal closes.
