Hi ​@Madan, 

Thanks for posting in the Community! Can you try to download in a Chrome Incognito browsing session?This often improves performance by clearing your cache and cookies and disabling your extensions. Additionally, sometimes this can be related to internet connection speed or network security. Can you please try again on another network?

Please review our Export Your Lucid Documents and our Troubleshooting: Export article from the Lucid Help Center. 

If you are still seeing the issue please provide:

• A description of the download settings (file type, document pages, cropping, quality, etc.) that you selected for the download.
• A screenshot of any error messages or pop-ups that appear.
• If the document will export but does not look as you expected, please send me the downloaded file and a description of what about it is incorrect, or a screenshot of the issue in the exported document.
• A screenshot of the associated Javascript Console output. You can open your Javascript Console by pressing Ctrl + Shift + J (if your computer is a Windows / Linux) OR Cmd + Opt + J (if your computer is a Mac)

Let me know if you’d like me to create a ticket so we can handle this more privately.
