You won't believe it! I've been trapped again on the "forbidden words" road!
My project is called "Control Center", and that was the issue
I just removed the space in the project name settings, and it works... 😰
So "Control" seems to cause issues when the app runs with OpenGL, and back in the days I had a similar issue because my plugin was named "System". I see that these names are somewhat clause to machine-reserved stuff, but I'm not asking for special chars, "Return true", or "?/:;#'" kind of names either 🙄
