Error unable to create directory

I’m trying to start a new project, but no matter where I want to save to, I get this error message: Unable to create directory: (folder location).

Please post a screenshot of where you are creating the directory and the name you are giving it.
Make sure you are not starting in the folder where the software is installed, you will not be
allowed to create anything in there.

Keep in mind to limit the naming to a-z, 0-9, “_” and “-”.
Do not use spaces, accented letters or special symbols in folder names.
