Error importing musicxml (from Cubase)

I can’t export musicxml from Cubase 9, and nor can I import from Forte.

Serious Error on both occasions. Also, Windows asking about administrative permissions when both programs are open.

There is not much information to give, it’s just a dialog that points to a Crash Dump file, which is of course Cubase related but I wanted to use the programs together, since Cubase does not allow a complete Score copy from project to project, I thought I’d try another program but I’m not having much luck thus far and am looking for alternatives at present.

I will try downloading a MIDI file from the web and see what happens but since I am having problems with MIDI import as well it means the program is not usable at present.

I’m on Windows 10 if that helps at all but now Dorico won’t open so I can’t test MusicXML from any program to Dorico.
