JavaFX won't run on Mac M2

[vsquared]

JavaFX code that ran without error on an Intel chip Mac (x86_64) no longer runs on an M2 system. This post is just for your information so that you are aware; the following error is generated by Thonny:

Interestingly, Error initializing QuantumRenderer: no suitable pipeline found is similar to the error message seen on a Windows system.

Javafx jar and lib files are kept in 'jars' folder inside of 'Python' folder which contains all of the .py files. These need to be replaced with a special sdk designed for M2 chip macs. Reference from StackOverflow is here: https://stackoverflow.com/questions/75147224/error-initializing-quantumrenderer-no-suitable-pipeline-found

The correct jar files for M2 may be downloaded from Gluon: https://gluonhq.com/products/javafx/

I used javafx-sdk-21.0.3 for aarch64 and compatible with jdk-17 and it worked:
