It work. However, INPUT side showed this: [[1,2],[3,4]]([1,2]), a display bug.

I seem to recall this being discussed here before but I can't find it now. Maybe it was somewhere else. It's clearly a display bug as turning off Textbook Display makes it display correctly.

I suspect this issue stems from xcas having 0-based arrays while the Prime has 1-based arrays.

I just filed a bug report.
