most likely you'll need java 1.8

@julian608 Do you know how I can change java version to 1.8? I have currently java 11 installed (as websites said that is the recommended?)

@julian608 It works after changing to java 8 thank you so much

You can set the environment variable JAVA_CMD to the 1.8 executable if you don't want to change the default system version

oh I already uninstalled java11... lol I use java just for clojure so I think i'm fine with just changing the system

I had the same issue when using 3d renderers with Quil (p3d or opengl)

I think java8 is like an industry standard or something.. I see a lot of program using java8 despite there's like so many now. But still not a java expert 😛
