Hello,
Sorry for your issue, but I am not able to reproduce this. I can use Console, Luna, and H9 Control with an H9 connected via USB without any issues or programs crashing. I have Console open most of the time whenever I am using my computer and have never had it crash when using H9 Control.
Does the crash happen if your H9 is not connected via USB when you open Luna? Can you try connecting the H9 to your computer with Bluetooth instead and seeing if that fixes the issue?
I’m using Big Sur 11.6 and Luna 1.1.8.2079.
