The same thing happened with my blog a few weeks ago. It was well referenced for years and suddenly almost all of my entries are not indexed anymore. The Search Console indicates that the URLs were crawled but are currently not indexed, and contrary to technical problems, there nothing I can do to fix it, I just have to accept that most of my articles cannot be found via Google anymore.

EDIT: I don't actually think it is related, but now that I think of it, the timing corresponds with when I started setting up TDMRep to forbid using my content to train LLMs.

Same. I've been running a personal blog for over 20 years. Last year, I couldn't find any links to my blog on Google. Went to Google Search Console to find all my links are "Crawled by not indexed", with no reason given.

If Google already slurped up any training data from your site, then not indexing it probably gives them something of a moat over anyone using Google search for site discovery.
