Starting Minecraft older than 1.19 crashes on Apple Silicon

[JXSnack]

My code

from portablemc.standard import Version
Version("1.12.2").install().run()

Crashes with

Traceback (most recent call last):
  File "/Users/joram/PycharmProjects/EastShoreLauncher/portablemc/standard.py", line 851, in _resolve_jvm
    with jvm_manifest_file.open("rt") as jvm_manifest_fp:

If I understand this correctly, it can't find the correct JVM. I tried using Zulu-8, so I tried this

portablemc start 1.12.2 --jvm /Library/Java/JavaVirtualMachines/zulu-8.jdk/Contents/Home/bin/java

but it crashed with
