I have grape hyacinths in a border area around our patio. Then in spring/summer I plant other flowers close to them, but the other
flowers don't seem to do well. Would the grape hyacinths affect the soil for this to happen?

They are usually fine with growing alongside other plants. I suppose it would depend on the type of other plants.
It could also be of some effect if the Hyacinths are overcrowded, and don't allow for any other bulbs to take hold.
Can you include more information about the types of flowers that you are trying to plant, and if this is shade/sun?
