The entire field of evolutionary psychology debunked? Do you mean the idea that our brains are subject to evolutionary forces like every other part of our anatomy? No, not debunked.
This is conflating specific methodological problems with theoretical claims. Yes, many have criticized the game theoretical methodology typical of evolutionary psychology. There are a lot of highly speculative junk claims out there. It’s also true that some (not all or even most!) cognitive scientists think that we cannot take the perspective that psychology evolved at all. But it is certainly untrue that there is some consensus that evolutionary psychology has been “debunked”.
This criticism is also a bit ironic given the highly speculative nature of the claims you put forward. Your guess sounds plausible I suppose, but I see no reason to think it’s any more methodologically rigorous.
