Hello ,
I’m here to help you in resolving your issue
Try Drag and Drop Between Windows with the Same Permissions
If you're dragging from a window running as Administrator to one that isn't (or vice versa), Windows blocks it.
So, Run both apps (File Explorer or whatever you're dragging to) with equal permission level:
Either run both normally, or Run both as Administrator.
After trying above steps, please reach out to me if you have any doubts or issues
