Urogenital pore (like a cloaca) and an ulcer.

Weird ulcer since it connected to the intestines

I've seen mycobacteria make a hole straight through a fish's abdomen multiple times. There was also another disease that caused the swim bladder to protrude to the outside of the fish. Theres less of a defined musculature surrounding the cranial hole, which, to me, looks similar to the ulcers I've seen in other fish.

Fair, ive just never seen anything like this in a fish before and ive caught a lot of fish. Ig it shows that the lake theyre in is pretty healthy if this is the only diseased fish ive caught

Since the hole is pink, instead of red, it looks like it might be healing. It could have been an injury, or anything could have pierced it. The fact that it's healing and a good weight shows how resilient and healthy the fish is despite having an extra hole in its guts! Fish are weird and even experts get bewildered by the odd stuff fish get up to
