error: "Swf compilation failed" - please verify actionscript

[#1]

(2019 Release, 11.5.5.553)
Sofware simulation (simple, excel) – no actions, variables,… only a few text frames with some instructions.
Publish as video – constantly the same error. (publish as HTML is passing but it is missing many transitions, mostly static).
So, 15 days can’t find a solution to use command Publish as video without problems (deleting cache, preferences, hiding some slides, working with only a few, one slide but always the same error, adding line Use32BitJVMForPublish = 1 in AdobeCaptivate.ini, no Onedrive nor any cloud storage,…)
Invested so much and almost 15 days producing nothing but blood high pressure, angry,…

Publish to video? You should have used Video Demo, not software simulation.

Do you have a lot of Full Motion Recording slides? They may be the culprit.

Thank you for your fast answer and for trying to help. I just made about 10 projects before and all published to video without problems. After deleting cache, preferences, and still not working, I recorded a new project (same theme). Recorded in about 10 minutes (when published to video it should be up to 15 minutes long). I just recorded formulas written in about 30 cells on 4 sheets. A few years ago, similar projects were much larger with more graphics and still worked. 
The error is so general and can be anything. This is not appropriate for today's stage of software development.

I would like to help you, but you didn't answer my questions 😞

BTW I am just a user, complaints about Adobe are not meant for me, I hope.

Sorry, maybe my words sound inappropriate. In the first project, there are 27 items named Fullmotionxxx.swf sized from 100 kB to 300kB per item. In the second project (same theme) there are 10 items Fullmotion but still doesn't work. As you recommended, I recorded it again as Video demo, and Publish to Video worked (added some explanation texts). For me, Sofware simulation gives me more options to manage this project than Video demo, but when it doesn't work I had to use Video demo (requires more preparation and time management). Thank you for your selfless effort to help a person in trouble.

Even if you use software sims, try to stop when you expect a FMR slide to be recorded, and insert one Video Demo slide instead. Not only will that be much better if you want to publish to video, but the quality will be way better, especially if you use 32-bit (Preferences, Recording) instead of the default 16-bit.
