Gray bar on right side of page on desktop

My site: https://angelazunigaphotography.com/

This is currently the only custom CSS I have : 

[class*='collection-type-blog-post']  .header-title-logo img {
  filter: invert()
}
.sqs-native-video .native-video-player {
    padding-bottom: 100% !important;
}

When I added : .sqs-native-video .native-video-player {
    padding-bottom: 100% !important;
}
to make videos vertical suddenly a gray bar appeared across all pages on the right side. I have tried removing all of the CSS and it won't go away. 

 

Can you share a screenshot? I can't see a grey bar anywhere.

@Ziggy Sorry for the late response, here is what I see: 

@Ziggy When I open an incognito and used a different browser, and it looked fine. I tried clearing my cache on google chrome to no avail though 😞 At least now I know it is just looking like this on my end. Thank you for the help!
