Because based on our current understanding of the physics of the universe, which is probably more or less correct, there is no way to stop it. It’s not an engineering problem like building a space elevator or a fusion reactor or spaceships to go to other plants. It’s a result of the fundamental laws of the universe. There is a finite amount of “fuel” available. I really recommend this video. It’s a Timelapse of the future and a real trip.

Technically we can move to a new universe if that tech ever exists

That could be possible. In which case this universe would still end in heat death. It’s also possible that we could create a new universe but have no way to travel there. Or potentially be unable to even verify that we were successful. We may even be living in such a universe right now.
