Thank You very much, that was indeed the problem. I would also like to catch your attention on something that I have been trying out and that is renaming the project, I have tried it several times without success following this guide : https://answers.unrealengine.com/que…c-project.html
And so far, it looks like there is still one area we still need to rename, but I don’t understand what it is. I have tried many times with and without deleting the saved and intermediary folders but to no avail.
