Hello ,
Thank you for contacting us on the Twinmotion community and would need to further look into this. This sometimes can occur at certain times depending on the location and AWS services in that location. Is the problem happening with a new simple file?
Please report a bug directly by using the Twinmotion Cloud from when using the [ contact us ] button from the home page or by following this link directly: https://twinmotionhelp.epicgames.com/s/case-community-page
Kind regards,
Vincent B,
