Hello there, after the initial setup of my c++ project that included playing around with build setting etc. I did not touch the projects settings anymore. After some weeks I needed to implement another library. It requires to access the project settings. When I try to open them via Clicking the top-most layer in the project navigator on the left (the name of the project), the tab of it opens, but it is completely empty. When I create new projects, this works. What can I do?
