Extruded component seems hollow/ empty

[Anonymous]

Hi, i'm new to fusion 360 and still learning, i have a problem with my extruded component being empty or it looks like it doesn't have a solid body, the first few times i'm using fusion this was not a problem as my extruded component doesn't looks like this (picture attatched) but the this problem comes up suddenly and i can't even change the appearance of my component, i attached the screenshot of my problem and the .f3d , i have googled and find no solution, if anyone can help it would be very helpful, thanks
