What does "Invalid serialized file header" even mean and how to get rid of it?

I know it's not a big deal, but having this error just pollutes my console and distracts me off of bugfixing. I'm having an issue with this error since months, and it is annoying. Here's the full error message:
> Invalid serialized file header. File: "library/metadata/36/364cbed7f93dcfe42aca88d373ca461b".
Does anyone know what does it mean and how to get rid of it? Thanks.
