Fillet Surface problem

I hope to fillet the surfaces on the toy car model for a more smooth form.

However, gaps are created after I fillet them.

Is there any way to fix this problem, or a better way to fillet those sharp edges? thank you.

First step towards fixing this problem would be to purchase an official license.
