Details below.

It used to work. Maybe new Macos updates broke it.

libusbJava.dylib is present.

The architecture of the Macbook M1 is aarch64.
Install Java aarch64 and not x86_64.

Thank you, that was it. I didn't know I already had a aarch64 JDK before I installed the Amazon's x86 version which caused the problem..
