Delete the TOC
Restart your PC
Add the TOC again, and regenerate.
If the crash still occurs, you likely have an issue with missing resources in your chapter files.
Open all files in your book and regenerate. If this works, then ensure your preferences do not mask any missing font or resource messages, resolve any such messages, and then regenerate.
Thanx Matt, the delete, restart, add solution worked!
Glad to hear! Make sure to mark as the correct answer to help others find it
