Looking for some help from Google seo expert to help our company site to identify this urgent issue. Here is the thing: the crawl request of our site experience a sudden drop on 9th, Oct. And it hasn't recovered yet. Daily crawl request drop from 6M to 60k (nearly 95%), but traffic didn't drop. This dropping trend showed in both GSC and our company's own log report.

We have checked the server and robots file, nothing wrong. And didn't notice any google algorithm update on 9th day. We would really appreciate it if someone can give me some advice on how to idenfity the problem.
