I got a list today, the name is list1. I can use %list1[0]% to get the data before the Power Fx function is enabled, but after I turn on Power Fx, the method will not work.%list1[0]% cannot get data.

If you want to use Power Fx enabled flow in Power Automate Desktop then you need to use Power Fx syntax.
It does not use the regular % -signs around variables or [index] to select item from the list or datatable (and many other things are different.

You could use First -expression to get the first item from the list:

Or use Index.
Index(youList, indexOfTheItem)

If you don't need to use power fx in your flows and are new to power automate desktop / power fx I recommend just using the regular flow. Its easier to find solutions and tutorials for since Power Fx enabled desktop flows just came out of preview.
