If that is the case it can be fixed and the FAQ here plus a search of the forum using "BER' will get you lots of info on it. But if you are talking about some sort of total fruit rot with accompanying diseased plants it is another matter. Could you provide more details and description of the rot and the condition of the plants?

Late Blight. Cause by a fungus that is favored by wet weather. Spores travel and can cause plants and fruits to suddenly rot.

Avoid crowding. Remove and destroy all infected plants.

Gardening zone/location? Are these tomatoes growing now or are we talking about last year? Late blight kills the plants, not the tomatoes, so were these plants ok in appearance? Maybe the fruit was just left too long on the vines? Picking at blush solves that problem.

Otherwise this is all just guess work and of little value in solving the problem.
