Well, your models are wrong. In both examples, you assume exponential growth will continue forever. Resource limits are a thing in the real world, as evidenced by every population in history (humans or animals).
Yeah, you assumed no catastrophic failures. On long timelines there are going to be world or civilization ending events.
There are so many species that were wiped out through their actions or just naturally. That’s the point of the Drake equation; the sky should be full of other civilizations, but it isn’t.
The common answer is that there may be a “great filter”, some event that all advanced species encounter. Maybe it’s ahead of us, or maybe it’s behind us. It could be something simple like “walking upright is rare” or it could be some powerful weapon everyone discovers.
