Yes it did work, around March/April I was working on some project for school using arduino nano and it all worked good. But in August I got my ardino uno r3 back from my friend and from then it doesen't work. Only thing i did was delete all libraries that were from previus project.
This are my properties for that file:
also this is code inside this .json file (i formated it with https://jsonformatter.curiousconcept.com/)
