It sounds like there was a more-or-less professional election rigger involved:
"According to prosecutors, McCrae Dowless, a contractor for the Harris campaign, oversaw extensive election fraud in Bladen County, in the district’s rural east, affecting potentially hundreds of votes."

He sounds extra sketchy.
A lot of these rules and restrictions are constructed in such a way that the dominant language/culture/homeowners don't have any problems meeting them, thus offering an easily defensible reasoning behind them. It seems totally reasonable to assume everyone has ID - but if you don't drive, and are well established in a community you probably won't need ID to conduct life.
The reality with the importance of the chief federal executive office and how the election swings on such narrow margins in certain states, this is a problem that constitutional we just aren't able to easily solve - deliberately so, that is the constitutional order constructed on purpose.
