Well maybe he needs to do more around the house but it’s really not your moms business (unless it’s her house). I can’t imagine telling my daughter what I think her husband should or shouldn’t do.

Perhaps you need to go low contact with your mother for awhile, see her less and talk less. If she asks why, I’d say I cannot allow you to criticize my house and my relationship and since you can’t stop, I need to limit our interactions.
