2019 Captivate - Fatal Error when recording with Custom Mode settings

I updated to the latest version of Captivate, and am now getting a fatal error when recording.

"A fatal error has occurred and the application is being terminated. Adobe Captivate has tried to save all your work...."

I have the issue narrowed down to the recording setting.  I use a Custom recording mode, to capture a "hybrid" version or simulation/demo.

In the Modes>Custom screen, I have selected the option to "Use Smart Shapes instead of Captions"

If I "deselect" this setting and instead use Captions - then it will record with the rest of the settings and no error is generated.

So there is an issue with using Smart Shapes in the capture.

Here is some other information:

1. I have been using this recording setting successfully on Captivate 2019 - this only started happening with the latest version release - which we upgraded to last week.
2. This is happening to EVERY team member on our eLearning design team (6 team members) - so this is not specific to one user
3. I cleared the CACHE in Preferences
4. I did the Clean PreferencesWin file in the utils folder
5. I renamed the Captivate 11.5 folder in the App Data - to Captivate 11.5_old then reopened Captivate, to force it to generate a new one
6. I changed the layouts folder on the C drive to force it to create a new one - and again - still have the issue (C:\Users\Public\Documents\Adobe\eLearning Assets) - found the folder called Layouts - renamed to Layouts_old - and restarted Captivate.
7. I have files setup to save to the C: and not a network location, so it's not a network connectivity issue.

Nothing has resolved. We have well over 100 learning materials - with several hundred more to develop over the next year - and really need the smart shape in place of the caption setting.

Any other suggestions of what to try?

(I did report this to Adobe support as well, via email - but I don't know how long it will take to get a response.)
