Bricked, cannot publish to HTML 5 with Upgraded from CP2017 to CP2019

I am a long-long-long time user (before RoboDemo).

My eLearning has been upgraded over the years from RoboDemo to CP and up to CP2017 and now CP2019.  Most of my content is circa 2008 and newer.

I converted all of my courses to HTML5 and that is deployed and running.

I use a GIF preloader at 25%

Auto-Play is OFF and I use images as the background for the PLAY triangle.

I use SCORM 1.2

ALL is fine in CP2017

All projects have clean HTML5 Inspector

Now I am playing with CP2019 and I cannot play any HTML5 output in any of my 128 Lessons.

I get the first slide, I get the play triangle and I press it and it advances to a BLANK page.

That blank page is just a cover page set at 3 seconds with no interactions, no transitions, no additional objects.

I run Preview as HTML5 in Browser and this happens.

I post to my LMS and this happens

Same with Chrome or IE11 or Edge

I hacked a few of these lessons up to get them down to just 2 slides, no video, no playbar, no Skin, Etc.

I disable the preloader and the START background image.

I inserted new blank slides as slides 1 and 2.

Nothing brings it to life.

NEW projects are fine, but that is not going to happen here because the settings, Quiz-Pools, Quiz Numbers, Etc. would be far too great of a chore to shovel over.

I absolutely cannot publish to HTML5 SCORM or HTML5 Preview in Browser with any of my 128 Lessons that make up 14 courses.  Bricked!

I can provide a sample to Adobe.  This needs a hot-patch now and not in a week.
