What kind of RAW file are you trying to load? It sounds like either the RAW format is not supported and I'm not catching / displaying the right error message... or it's a 48 MPX iPhone 15 Pro RAW file that silently crashes Safari. Because that's what happens but it's not my fault. Safari will not allow opening images larger than 16 million pixels. That's a hard limit artificially imposed by Apple and there's nothing I can do about that. Images larger than that will silently crash the browser with zero errors or warning messages. Apple likely does this to protect their native app platform where they can impose a 30% tax. All we can hope is that legislators will continue putting regulatory pressure on them to allow alternate browser engines which don't have these kinds of limitations... If you're in the EU you'll soon be able to use alternate browser engines that won't have these restrictions: https://open-web-advocacy.org/apple-browser-ban/
