Very strange corners

Hello, everybody. I have a somewhat annoying problem that I am struggling to solve. Here is my print with PETG, and as you can see, the overall print is fine except for the corners. For some reason, they look like this. Does anybody have any ideas why? I would appreciate any help. Thank you!
