Captivate 2019 freezes during publishing

Good day to everyone,

I am using a newly installed version of Captivate 2019, and attempting to publish a lesson to HTML5, into a folder located on my desktop, part of the main drive of my computer.  However, during the publishing process, the system gets stuck in the Optimizing Content phase of publishing... and never completes the publishing and zipping of the file. At that time, it also slows down my computer from the state-of-the-art, fresh-out-of-the-box Core-I9 super highspeed laptop that it is, to something more resembling an i386, circa 1997.

I have looked through the forums, and on Google, but I still have not been able to find an answer on how to fix this.  I would value any suggestions you amazing professionals might have on how to resolve this issue.

Thank you!
