Sorry that you're having trouble while exporting to After Effects from XD. We have an on-going discussion on a similar topic, would you mind joining this discussion here: - Unable to export from XD to After Effects and share your inputs? We would really appreciate if you could run the log collector tool as per the instructions mentioned in message #14. After you run the log collector tool, you will be provided with a link to the log files. Please share the link over here.
In addition to this, please re-install Adobe XD and check if that works for you.
