Since ClosedXML is an open source project, the simplest way of tracking the error down would be building it from the source ^*, and then running your code against the library in debug mode.

Once you see the full stack trace, you should be able to identify the spot from which the error is coming. Good chances are that it is a bug in the way the ClosedXML project uses Microsoft XML libraries, because the error that you mentioned is reported by a library outside the ClosedXML project.

^* I downloaded the project, and tried building it. Everything in the closedxml-79843.zip package builds correctly.
