Why is an error in SEMrush not visible in GSC?

Hello, I have a quick question. In SEMrush I get an error saying a page cannot be crawled, but in Google Search Console no issue comes up. Should I trust one tool over the other or is it best to just check the issue. The page was recently redirected so I will check, but I’m just trying to understand the inconsistency between semrush and GSC. Any advice? Thanks
