I have the core plugin installed above it and both are the most updated version. I'm using a Mac instead of PC, so pressing F8 or F12 simply closes the entire playtest window. I'm also just now seeing that some other people have been reporting issues with the Console not opening on the Mac version, since more than 3 years ago... It had always worked before that, but now it just closes the game. Still trying to find some way around that, but I have a looooooong list of plugins and this is the only one that simply doesn't work at all, even in an empty project.
