What does the serialized link look like?

I imagine the reference should be read as proxy and resolved later, if
it's not resolving, I need more details to understand why. It should be
fine that it's an AnyType while it's a proxy, so likely the problem is
more to do with resolving the proxy than anything else.

Ed,
Indeed, it was unrecognized content. Different uml versions.
So it was not a reference problem.
Thank you anyway.
