With such long periods of time in play (if we succeed), the improbable hellish scenarios which might befall us become increasingly probable.
With the probability of death never quite reaching 0, despite advanced science, death might yet be inevitable.
But the same applies also to a hellish life in the meanwhile. And the longer the life, the more likely the survivors will envy the dead. Is there any safety in this universe? What's the best we can do?
Robert Ettinger wrote a story in 1948 called "The Penultimate Trump" in which the main character, the first cryonicist, awakes seemingly trumphantly only to be sent to Hell in punishment for his crimes.
