Box Element causing overflows on smaller screens, even though it does not reach the end of screen

I am using Material UI with React and Webpack On smaller screens my react box component makes the screen "expand" on the right side, and this causes the navbar to expand, and also horizontal scroll to appear, I have attached my return code, and also a few screenshots that may help. My element
return (
<div>
{/* Name "input" panel */}
<Container>
<Box
sx={{
maxWidth: { xs: 350, sm: 480, md: 600, lg: 800},
borderWidth: 15,
borderStyle: 'solid',
borderColor: 'background.paper',
borderRadius: 4,
boxShadow: 8,
backgroundColor: 'background.paper',
'&:hover': {
backgroundColor: 'background.paper',
opacity: [0.98, 0.93, 0.9],
},
}}

Some screenshots of the issue: https://i.stack.imgur.com/gtmJE.png As you see on the "right side" of the view, the different grey colour appears, and that is the place where the element overflows. You can view the issue here: https://dev.vinu.cash/nameLookup (visible on mobile devices, on chrome selecting Galaxy S8+ (360x740) device to view on also shows the issue.

Yeah, it only happens on smaller screens can you try on chrome on desktop with samsung s8+ preview?

Nope, both didn't help When I remove the box component, the overflow disappears so something with it also happens in other places I have the box element
