Crawlers can’t find internal links in my site

I went to generate a sitemap for my site which have a lot of internal links as you can see in that image.

When generated it doesn’t include any of my internal links but my homepage URL which you can see in that image.

Then crawled my site with Screaming frog SEO spider and it gave the same result (no internal links found).

I didn’t block all of my internal links using robot.txt just a few links I don’t want them to be crawled.

I don’t know what’s going on. Please tell me how can I fix this. This is my site if you need it.
