There are a few reasons why your apple strawberry crisp might be soggy. One reason could be that you over-mixed the ingredients. When you mix the dry ingredients with the wet ingredients, only mix until everything is just combined. Over-mixing can make your crisp soggy because it makes the topping wetter. Another reason your crisp might be soggy is that you didn't bake it long enough. The crisp should be golden brown and bubbly. If it's not baked long enough, it will be soggy. Lastly, if you use too much fruit in your crisp, it can make it soggy. Be sure to use the amount of fruit specified in the recipe.
