Have similar issue with 2020.01 (15.0.2) update. Adding a cross-reference between two documents in the same book works fine the first time, the second attempt to add a cross-references never opens the dialog and freezes InDesign forcing me to crash it out. Saving and closing both files after each addition clears whatever it is, allowing for one cross-reference to be added when you open the files again.
