Hello, I wanted to make a new test on my macbook arm64.
I built PhysX with jni natives and it went good.

But I can't run the demo, even with the argument/VM option "-XstartOnFirstThread" on Intellij, it crash at start:

I really carefully check if the VM options was valid, and it if it is interpreted at the launch.
Executing task ' run -XstartOnFirstThread'

It is really strange, does it launch for you on a macos ?

Thank you in advance, I really liked the demo update of the island =)

EDIT: SOLVED
I added jvmArgs("-XstartOnFirstThread") in the gradle run task

Hmm still a bit odd that this only occurs on arm64 / macos. But good to know there's an easy fix.
