I also tried installing a different version of OpenJDK from the link in the README and had the same output there:

Hi,

Thanks for reporting the issue. I did some research and this appears to be related to that JNA version not supporting the Apple Silicon architecture. I'll update JNA to a newer version which should resolve the error in the next release. If you want to update it on your own as a provisional workaround, just replace the JNA bundle with 5.7.0 or newer and update the manifest.txt to include the library's path. I only have access to x86 Apple hardware, so I cannot test.

Unfortunately it may not be that simple. I am guessing that JNA might have some breaking API changes, because it changes the error to:

I was able to reproduce that exact error in 2.2 after replacing the JNA library. I updated the upstream serial library for the new API bindings and I no longer got errors with the newer JNA in v2.2.1 which is now posted. Now that it launches, 2.2.1 should support your M1 arch. Let me know if you still get errors.
