Win11 Can't drag files into open app windows on taskbar

The blocked pointer means Windows or the target is rejecting the drop; restarting Explorer alone will not distinguish the cause. First open one affected app normally, not with Run as administrator, and drag a supported file directly into its visible window. Explorer normally runs at standard integrity, and Windows security prevents lower-integrity processes from sending some interactions to an elevated target. If direct drag works only after removing the app’s compatibility setting to run elevated, that is the cause; do not elevate Explorer as a workaround. Next drag a text file into Notepad directly, then repeat by hovering over Notepad’s taskbar icon. If that works, update the third-party apps because each target must advertise and process supported drop formats. If every target fails, perform a clean boot and test a new local profile. If a clean profile also fails, report the build through Feedback Hub.
