Drop camera in deionized/distilled water without battery. This will hopefully clean the camera insides including the lens element that has fogged. Remove camera, drain for 1 day over paper towel rotating every once in a while to dislodge puddled water. place in oven at 150F for 30 minutes on hotpad so it doesnt get full heat of metal contact. Next, place camera in bag of rice or other desiccant for a week, ou cna put in fridge too as that air is very dry. After you take out of fridge, warm to room temp for a few hours and then you are ready to cross fingers and put battery in. If all goes well, your camera will come back to life. The lens may still be dirty but that is a physical cleaning operation.
