This kinda feels like the definition of incon. Neither can kill each other through AP, so it's down to hax. Crawler doesn't have any hax on base that would meaningfully do anything to 682, while 682 seems to have Absorption and Black Hole. The Black Hole according to the scans seems to have come out when 682 was in substantial danger, so it's not likely to be a first move at all. And without context, absorption would likely be overtime or through chunks of material, which would give Crawler time to adapt defenses to it, and likely gain a mutation through it to acquire a new hax. This is then of course used on 682 who likely wouldn't die/be incapacitated for long enough by said new mutation, and would then adapt and RE to it himself, and the cycle would just kinda continue until one finds a way to do something impactful. Sure 682 would have black hole creation, but the scans don't show it doing any substantial damage, at least not enough to assume it would insta kill something the size of Crawler, so he would have potential to survive it and maybe adapt. There's too many questions and unknowns of how the adaptations each would acquire would end up working. So this just seems like a massive incon.
