Cannot bind App State (String) to Image Path – option is shown but not clickable

I created a String App State variable called selectedPhoto to store the photo path from either camera or gallery.

The image preview should change dynamically based on this variable. However, when I try to bind it to the Image widget’s Path field (Set from Variable > App State > selectedPhoto), I can see the variable listed — but I cannot click or select it.

No error message appears. It just doesn’t respond to my click.

I already confirmed that the variable is getting updated correctly after using the “Store media for upload” and “Update App State” actions. But I can’t link it to the image widget.
