Robohelp 2020 - Stuck At Indexing references

I have been maintaing this particular Help system since the Macromedia days, I have generated this Help in almost every Version of Robohelp since X5 and was able to generate it in Version 2019 New UI but an earlier Build than 14, not sure which build though. I just created a new TOC with a single topic and it appears to be stuck on it, although I will give it some more time.

There was a fix for one of the issues behind sticking at Indexing References. Since then I have looked at a couple of projects and the issue has been a topic with some code RoboHelp doesn't like.

In the last one it was a topic that I think had been pasted in from Word that referred to styles that weren't in the CSS.

The only way I think you are going to find the cause is this. You create a new TOC and open it in the Authoring area. Don't worry about creating books, just drag topics or folders from the Contents panel. Try say 10/20% of your topics. Then see if that will generate.

• If it doesn't start deleting sections from that TOC and generate until it does.
• If it does generate, add more until it doesn't.

When you can pinpoint a topic, we can look at it.

I have to ask, if you had this problem in 2019, how did you generate anything?
