Hi Julieg, thank you for reaching out, I'll try my best to assist you with it.
Please share the version of XD and OS build which you're using? Ensure that you have updated to XD 35.2. If You're already using XD 35.2, please collect the logs using this link:( https://helpx.adobe.com/creative-cloud/kb/cc-log-collector.html ). You may upload the logs to CC or Dropbox and share the link with me via PM (Go to my profile and click the "Send a message" button). I'll escalate the case with the product team.
