QB Desktop Pro 2017 crashes

I am using QB Desktop Pro 2017.

When I entering an invoice, I select the customer, select the product and when I enter a quantity and use the + sign to add more to that quantity, QB just closes and I get no error message. When I enter one quantity on line 1 and another quantity on line 2, QB doesn't close and there seems to be no problem. Why does QB crash when I use a + sign?
