What’s really interesting for me and something I haven’t been able to find good literature on - is how the civilization seems to severely regress into the dark ages after the ancient times.

While Rome fell, Byzantium continued on. The state even continued to refer to themselves as Roman.

Certain construction items change and have good explanation, such as the Roman concrete - it’s volcanic components were no longer accessible to Byzantine builders, so the use became impractical.

But how did we manage to lose the knowledge behind the Antikythera device and why was it not recorded?

Rome itself was partly/largely to blame - the idea of a unified greco-roman culture is a myth. When thinking about ancient science and technology, its useful to divide antiquity into three periods:

the classical greek period 600-350 bce

the Hellenistic Greek period 350 - 150 bce

the 'imperial' period 150 bce - whenever ce

Virtually all of the great scientific and technical achievements of antiquity were from the Hellenistic Greek society - the society of euclid, eratosthenes, archimedes, ctesibius, hipparchus, chrysippus, herophilus, supported by the Ptolemies in north Africa.

All this scientific work came to an abrupt end around 150bce due to the roman conquests, and the political atmosphere they created. Carthage (itself a cosmopolitan center of learning with close ties to the greek world) was not he only north african city razed to its foundations by Rome. Its easier to list the survivors: (1) Alexandria and (2) Rhodes. This completes the list. And the academics didn't survive: in 145bce Ptolemy VIII persecuted the city's greek elite so all the intellectuals fled, and the romans made a hobby of enslaving greek intellectuals, to have them work as copyists and teach their children to read.

Thus in a very short span of time, virtually all of the physical books were destroyed when the cities were destroyed, and the intellectual culture that understood the ideas was eliminated. There was a partial renaissance during the Pax Romana (ptolemy, galen, etc), but the understanding of the science was much more primitive and quickly faded with no state and cultural support.

As for technology - roman engineering was typically less advanced than greek engineering, and for technically difficult things the latin writing are both crude and wrong: their scientific engineering was done by importing engineers from the east. The antikythera mechanism (late 2nd century bce) is a good example of the decline: there is nothing of comparable mechanical complexity from the roman period, neither in archeology or in Heron.

See Russo[1] for very readable up to date academic scholarship on this kind of thing.

What Russo has to say about Seneca and Eratosthenes is shocking
"But how did we manage to lose the knowledge behind the Antikythera device and why was it not recorded?"

The idea that one should share ones inventions is not universal. While other wrote profusely, other ancient sages often guarded their discoveries fairly jealously.

I'm pretty sure lot of pre-20th century discoveries have been discovered several times by various people, but the surrounding society has not benefitted from their knowledge for various reasons.

An excellent example is Leonardo da Vinci. If this question irks you, I warmly suggest you read Isaacson's biography of him.

Leonardo discovered several scientific principles hundreds of years before his time, including Newton's third law, and the fluid dynamic operation of the human hearts aortic valve.

But since he never published anything, references to these were dug out only by latter day historians, and did not benefit his contemporaries.

Biomaterial Books have to copied to survive the centuries. First the knowledge has to be written down, which was not the uniform practice in pre-scientific craft guilds. Second it has to be deemed significant enough to be worth expensive paper and hand-copying. Certain classical texts were deemed significant by Christian monks and Arab scholars to preserve by copying. But many were not.
