The concern about microplastics is that they are literally everywhere and we're not really sure what their effect will be, but so far, they seem to disrupt living organisms. It's best to not think of societal collapse just in terms of things that directly affect humans, but also all the biological systems (e.g. agriculture) that we rely on.

And we've had these microplastics in the system in the 1950s. If there was some civilization threatening content in microplastics, we'd know having several generations born and raised in that environment.
