Just want to mention that
LogicPro 10.8.1 with a instrument track and the try to load an AU-instance of HalionSonic freezes and forces the M1Pro MacBookPro 16" to re-started.
Congrats to Steinberg: you made it the first! Last 2,5 years this machine never had to hard reboot with 10-14 hours daily usage for work. 
macOS Sonoma, newest
LogicPro 10.8.1
HalionSonic 7.1 downloaded July 2024
Possible problem:
- DAW was running and a region with midi notes on that track
- LittleSnitch opened up as HalionSonic wants to connect to a server
Report of crash sent to Apple already.
Hope this information helps. Won’t use your product for now anymore.
