Issue in 2022 Photoshop with saving slices for web

[Zahra5E4F]

I have a jpeg that is 1100 height by 450 px wide. I want to slice it into multiple slices, each being 450 px wide. However I keep getting this error message. Please help?!

When do you receive the error? when you click save? Where is the value entered prior to getting this error dialog?

After I go to Save for Web, the percentage panel won't let me surpass 71.77%, so the width is forced to stay at 323px or less. I also reverted back to my 22.5.2 version, and am still having the issue. I even tried exporting different documents of this size to see if it was a file corruption issue. But it is not.

The original jpeg file itself is 450 px wide

can you take a screenshot of the entire SFW window with your document open in it?
