It’s hard to say for certain what this issue is but there are a couple of good possibilities.
It could be tarnished plant bug. To be sure you would have to actually see the moths or the nymphs.
It could also be poor pollination because you had only one plant. Attached is a good overview of how to grow raspberries in the home garden. Raspberries are heavy feeders so be sure to fertilize for a good crop.
Also, depending on what kind of raspberries you are growing, be sure to prune them this fall.
