IE 5 came out in the late 90s, it doesn't load websites very well because website standards have changed over a span of 20 years. Even if it loaded, say something as complex as the Apple website, it would be incredibly broken and formatted horribly
please, don't use IE 5 for any real web browsing in 2022. It's a great time capsule, but doing real things in it just isn't going to work
