Hello ,
Thank you for posting in the community and sorry to hear about the troubles. I believe there is a setting in Maya to change the up axis from Y to Z or vis versa. You may want to check that setting and see if that makes the difference. https://forums.autodesk.com/t5/maya-ideas/y-up-z-up-maya-preferences/idi-p/8570794
Hope this helps and let us know if that worked.
Kind regards,
