Hello ,
Thank you for posting in the community and sorry to hear about the issues you are facing. At this time we do not support Ventura and it could be the source of the issues. What are the issues you are having with the Quixel libraries?
Could you confirm what version of the Datasmith plugin you are using by following this link:

In order for us to best investigate if it is Ventura specific, please report a bug and provide the information requested in the form: https://twinmotionhelp.epicgames.com/s/case-community-page
Looking forward to hearing back from you.
Kind regards,
Vincent B.
