    ComboboxCanvas1.Selected only handles one item — but if you're using multi-select, you need SelectedItems.
     
    Try this 
     
    CountRows(
        Distinct(
            Filter(
                'CHECK LIST',
                'ID CHECK-LIST' in 
                    Filter(
                        'SKILL MATRIX',
                        'ID SAVOIR FAIRE' in 
                            ForAll(ComboboxCanvas1.SelectedItems, Id)
                    ).'ID CHECK-LIST'
            ),
            'ID EMPLOYES'
        ),
        'ID EMPLOYES'
    )
     
    If its only single select 
     
    Try this 
     
    CountRows(
        Distinct(
            Filter(
                'CHECK LIST',
                'ID CHECK-LIST' in
                    Filter(
                        'SKILL MATRIX',
                        'ID SAVOIR FAIRE' = ComboboxCanvas1.Selected.'Savoir faire générique'.Id
                    ).'ID CHECK-LIST'
            ),
            'ID EMPLOYES'
        )
    )
