Key Issues:

General UI Lag: Clicking between slides or menus is delayed and often “hangs.”

Audio/Text Desync: When adjusting text boxes to narration, the audio continues to play but the UI/subtitles freeze for several seconds.

Overall Stability: The app feels unresponsive and struggles to handle the project size.

What can I do to resolve this issue?Because currently the app is unusable for professional production.

When I read this I think that it might be one of several things.

  • Adobe Captivate has some demending system requirements. You are going to want a multicore Intel® or AMD processor (2 GHz or faster processor) with 64-bit support, and at least 16 GB or RAM (I have 64 GB just to be sure).
  • Adobe Captivate project files contain all the media elements that you have added to your project, even media that you have deleted because you changed your mind. Click on the File dropdown menu and select Remove Unused Items. Save the project and pay attention to the file size before and after. If it gets reduced by a significant amount, this might be the problem.
  • If it’s available to you, perhaps click on the Help dropdown menu and select Check for Updates. New releases introduce new features but also fix bugs and improve the application in other ways as well.
