SF vs GSC

I audited my website and found some discrepancies. Screaming Frog indicates 79 internal URLs with the 404 status while (GSC) assigns 5020 (404 not found) URLs there. How is this possible? Does Screaming Frog navigate internal links page by page, while Google discovers URLs in a different manner?

When it comes to SF you´re referring to internal links being broken? GSC shows HTML pages returning 404 HTTP errors. Maybe those pages are orphans.
