Here is an interference between the hinge and the body. Resizing the hole where the pin goes will cause interference.
Two options, remove the material or move the hinge outwards .
Just put a simple rectangular extrude cut in the body of the box & another in the door if need be.
I'm trying the extrude cut. I keep cutting the hinge because it's in the exact same place as the part of the body I need to cut. Even if I hide the hinge it still cuts it.
Do not cut in assembly but open the part and then add the cut.
Edit the part within the assembly if you want to use the hinge as reference. Don't add the cut at assembly level, if you do make sure you pick the body to cut. Or open the part & add the cut there.
