LightOccluder2D don't work

Godot Version

v4.2.2
I’m on Mac

Question

Hi there!
I have a problem with LightOccluder2D. I can’t get them to work at all, even though the mask matches and the shadow property is enabled. However, on another computer, I managed to do it without any problem, and even exporting the project to another computer makes it work. So the problem seems to be with mine, and I don’t understand why. I uninstalled and reinstalled Godot4, but it didn’t work.
I don’t know if this has anything to do with it, but I also have a problem with BlendMode, where Substract has exactly the same effect as Add.

Do you know how I could fix this?

If it works on one computer but not the other with the exact same settings then you should open an issue at Issues · godotengine/godot · GitHub
