why the disabled field of the mat-checkbox component may not work

I need this component to accept the disabled value depending on the variable, the most common use of a component. But it does not work, I did everything as in the documentation

I imported the module as in the documentation, the component itself worksenter image description here but field with disabled doesn't work it doesn't matter if disabled is set through a variable, or through true - nothing Ыetting disabled form formGroup works, but i can't enter a specific condition there
