Update Angular 14 to 15: mat-pseudo-checkbox no more visible

I have to update my web application from Angular 14 to 15 but I have a strange problem, my mat-pseudo-checkbox (code below) is not more visible.

<div>
   <mat-pseudo-checkbox (click)="itemSelect()" [state]="isItemSelected()"></mat-pseudo-checkbox>
Test

In Angular 14 the "mat-pseudo-checkbox" was visible. If I change the code with "mat-checkbox" the checkbox appears. I have not CSS relative the "mat-pseudo-checkbox" and I'm not able to find any informations about the porting from 14 to 15 for the "mat-pseudo-checkbox". Can someone help me?

Thanks in advanced
