Unable to read sitemap

I can’t seem to get Google to read my Yoast SEO sitemap (WordPress plugin). I’ve even tried reloading it several times over the course of several days, but it remains stuck as the last read on September 23.

Basically, the primary sitemap is read
https://tinyurl.com/2mnjthvv

but the secondary ones aren’t…
I’ve searched everywhere for information, but I haven’t been able to resolve the issue…
Could it be due to Litespeed? I’ve also activated the CDN on quic.colud.
