My website is having very low daily average crawl requests (~20k/day) whereas approximately 300K pages are indexed.

I want to change my domain in the Google Search Console. First, I set up a 301 redirect for my old domain and all its URLs, then moved the website to the new domain. I checked most of the old URLs to ensure the 301 redirects were working fine. However, after 3 weeks, Google still could not fetch my homepage to accept the redirect and update my domain.
additionally, google change my SERP Addresses to new domain in most of results.
how can solve this issue ?
