I've tried to take a look onto X3D reader in development branch of Assimp library to see if there is a difference in reading this file,
but instead observed just a laconic commit "3MF: Migration" just removing the whole parser (but not import plugin itself) in the August '2020:

Don't know how X3D could be related to 3MF - probably authors wanted to refactor all XML parsers in the project, but forget putting a TODO to removed code...

Seems X3D reader has been finally rewritten in Assimp - will need to check if it is still affected by this bug after Assimp 5.1 release:
