Fatal Error while publishing in Captivate 2019

We are trying to publish a file in SWF/HTML, and also using SCORM 1.2 for publishing.
Trying to create SWF and HTML together is giving me the error as seen in the screenshot. We want to make it compatible with the LMS.
One solution I have for this is to copy all the slides with audio and animation to a new source file and publish. This is still tricky, as I have some rework on the small setting completed on each slide. The audio was coming up well on all slides.
Is there another resolution to this? is this a known error.
