Black Screen when launching game in Full Screen (SOLVED)

[Sleepy]

Hi, I've been working on a demo and have run into a very particular problem. I accidentally quit the game when I was in fullscreen mode and now every time I try to boot it, because the default has been set to fullscreen, it becomes locked on a black screen (though I can still hear the main menu music for a while). I've been able to somewhat get around this using my windows build of the game but if I try to launch the mac build or use ren'py launcher on my mac, the problem occurs.

Is there any get arounds for this, such as forcing the game to launch in windows mode?

For ref, I'm updated to Ren'py 6.99.

EDIT:

Managed to fix by deleting the persist data. However, lacking X11 on Macs seems to cause the bug to occur.
