Hi, I just updated this morning (5.0.7 1199) and afterwards the Visionaire Player broke. I was only seeing a black screen, but I was getting sound and interaction(walking) seemed to be working.
However, when I entered window-mode and I moved the window just a little bit, the graphics showed up and stayed up.
More information that might be useful: I'm on a Mac (Mojave) and the previous version was working fine just yesteday. I've tried with both my own project and the Fantasy Quest demo, with the same result.
