Hi @Steven
From your image, I see that you are using macOS 27. macOS 27 is still in beta phase and Mac beta releases aren't supported in this scenario.

I also tested on macOS version 26.3.1 and I am still able to tick for OneDrive preview. You can also notice the UI is also different.
So, if you want to get Insider Preview, you can consider revert back to macOS 26.
I hope this information helps.
