While you have an interesting point, it is an invalid analogy:
After the fall of the Roman Empire that part of the world involuntarily fell into a dark age, that is very different from intentionally eschewing technology. And those societies did rediscover most of the lost knowledge and began progressing again.
Presumably a society with advanced technology that did something as drastic as getting rid of all of it would have left behind reasons so that their ancestors would also avoid it, or at least be able to make an informed choice. It would not be hard to ensure that endured (barring a major catastrophe) for many generations.
It could have taken the form of oral histories which can be preserved (at least in general intent, even if details change) for very long stretches, or maintaining writing even if it was restricted to their spiritual leader caste, or even one remaining piece of technology in the form of an extremely durable recording that speaks to them on set anniversaries.
Giving up technology is very different to losing it as a society collapses into a dark age from a combination of corruption, war, and other factors.
Also, the Roman Empire did not have anything to function as an ancestral memory. While it has been mentioned several times before that the limits of the Soul Trees function as an ancestral memory were left vague, it seems likely that something as fundamental as deliberately eschewing technology would show up at least as echoes of an aversion to technology.
