I am trying to get started with ReactJS and I have watched a beginners Pluralsight course. I seem to be falling at the first hurdle. Here is my HTML (index.html):

PS: yes, I already tested many configurations and things I found here, like this topic: VSCode Intellisense, snippets, suggestions are not working in JSX, TSX files

I tried to import a file into a code but the foulder could not be found.
However when i try to type the name of the folder out it already suggests me the folder and recognizes it as such.
I also already have tried out to write the entire path out but the result is the same.
