macOS 15.2, InDesign 20.0.1

When I generate or update a TOC there is a roughly 7 in 10 chance InDesign 2025 will crash. This happens with multiple documents and has been happening consistently with every document since the release of 20.0 in October.

• I initially thought it was because I was using ID '25 on macOS Ventura, but it's still happening with existing and new documents since updating my Mac to Sequoia.
• Additionally, the same files moved to other computers (Windows 10, for example) also crash there when generating, updating TOCs.
• Happens whether the documents in question are standalone or booked, with or without other TOCs in same document, with and without other documents opened.
• No problems with ID '22, '23, or '24 on the same computer, with the same content in new documents or with the pre-existing documents that had pre-25 file versions.
• Happens with vanilla, plain text headings (no GREP styles, no Xrefs, no text variables).

I had hoped that all those literally more than 100 automatic bug reports would have had Adobe fix the problem or reach out to me for info, but no. My own troubleshooting hasn't turned up the culprit, so I'm asking the community for help.

It literally took me a (work) week to generate the table of contents for InDesign Masterclass: Type & Tables: 2025 Edition (and actually delayed the publication of that book by more than a week) because InDesign crashed every single time, hour after hour, of trying to generate  the TOC for the INDB book of 12 INDDs. If I hadn't needed to teach MathML in the book, I wouldn't have used InDesign 2025 at all, and would have reverted to '24.

For InDesign Masterclass: Text Techniques book I lost ALMOST a week with the same crashing. In the end, I built the table of contents by hand, line by line, hyperlink by hyperlink, instead of using InDesign's built-in TOC feature.
