Just happened again today B286. Timestamp 7/30/2024 9 AM - 12 PM EST.
@michael please let me know if that timestamp helps?
Edit: Happened again today, had to manually kill the app. 8/12/2024 9AM - 11 AM EST.
Edit 8/15/2024:
This is solved for me. It’s a bug with the Now Playing and Queue screens where there is runway GPU usage. Leaving ARC on any other screen when idle solves the power draw issue.
