When low-tech societies collapse, the reason is typically that they lose access to some resource that’s essential to their way of life, and they can’t adapt because their technology base doesn’t include anything they can switch to as a substitute. Since the number of potential substitutes for any given resource grows steadily as technology advances we would expect more advanced societies to be more resistant to that type of problem, and indeed that’s what we see in the historical record. If you can’t keep the nuclear power plants working you can always fall back on oil, or natural gas, or coal, or hydro, or windmills, and so on all the way down the chain to bronze age power sources. Then, once you find a level you can sustain in your new situation, you can start rebuilding transportation and industry to get back to where you were before the disaster.
Which is why I say that the “big disaster causes civilization to collapse” scenario is fictional evidence. AKAIK it has never happened to any society that had even colonial-era tech, and there are good reasons to think it can’t unless you posit such a high casualty rate (>99%) that instant extinction becomes an equally plausible outcome.
