I don't know if this is the full code or reduced for display but there are a couple things I would suggest looking at:
Your View is not valid. You can't put a bunch of Text() views directly in the body. Try putting a VStack around the ForEach loop.
Inside of the dataTask block, make sure that the data object is not nil. You are force unwrapping the optional, but without ever making sure that it isn't nil.
