Just to update here, this might be helpful.
SC had my 23MYLR Friday 15th. They spent 3 full days trying to fix the firmware but no success. Finally, they replaced the FSD computer. I got my vehicle back yesterday 12/20. with 2023.44.1. It was working fine until there was another update last night, the holiday update version 2023.44.30.4. After the update, Autopilot failed again.....
Called SC and they pushed the same firmware update. It's working fine now.
