Acrobat Portfolio - Excel preview blank

Windows 10 Enterprise, version22H2

Acrobat Pro version 2024.002.20858 64bit

I created an Acrobat portfolio with a single page PDF and an Excel spreadsheet.

When I select the Excel spreadsheet on the left, it gave me the option to Preview it or open it.

I selected Preview but it's a blank page. I cannot get it to show this option afain.

At top, it gives me the option to Open it.

How do I get the Preview to actually show something?
