Hi everyone,
I am a new user of Obsidian, and I have been using it for the last week. Today, after opening Obsidian and starting to write a new note, I tried to drag and drop an image to the note, but nothing happened. I changed to another vault I created before, and then drag and drop did not work. Lastly, I went to the Help vault, and there I could drag-and-drop the image normally.
I, then, tried to put all configurations in both vaults I created to be equal to the help vault. It still didn’t work. Next, I uninstalled and installed the software, and nothing. 
My operating system is Windows 10.
Does anyone have any idea on what I could do to make it work?
