Thanks for trying Riddhi. Could you please try splitting your artboards into two separate files and then retry. If that doesn't work either, please share the file on which you are getting the error along with system logs https://helpx.adobe.com/creative-cloud/kb/cc-log-collector.html
Please add the XD file and the logs file to a shared location like Google Drive or DropBox and share the link through DM by clicking on my name, we'll try our best to help you with it.
