That is most likely because you do not have the latest plugin versions. Can you hit f12 to see the console and see what error it is logging when it tries to open it? Also make sure you have the latest versions downloaded of each plugin.
that is related to the light effect add on. Please update it to the latest version you can download from the itch page and it should work.
Good Luck!
