Hello @Viri 

You can write onChange client script on "Assigned to" field

function onChange(control, oldValue, newValue, isLoading, isTemplate) {

    if (isLoading) {

        return;

    }

    if (newValue == '') {

        // for pop up

        alert("You have just removed Assignee...!!");

        // or you can show field ,essage as well

        g_form.showFieldMsg('assigned_to', "You have just removed Assignee...!!", "error");

    }   

}

Output : 

Alert Pop-up 

Field Message :

Try using the below on change client script on incident table, where field name = Assigned to. I have given both the options of alert which is a pop up box (or) you may consider using field messages.

function onChange(control, oldValue, newValue, isLoading, isTemplate) {

    if (isLoading) {

        return;

    }

    if (newValue === '') {

        alert('Existing Assigned to user is removed');

        g_form.showFieldMsg('assigned_to', 'The "Assigned to" field cannot be empty.', 'error');

    }

}

Let me know if this works for you
