It’s a bit annoying but you should be able to see in GSC what the ranking change was for particular URLs and queries by comparing before October and after October. You should also be able to see if the issue is whether the pages dropped in ranking or if some articles became de-indexed entirely. Take one of the page URLs that has dropped in traffic and make sure it’s still being indexed.
