Watchdog Hard Fault on Pixhawk 6X Pro during compass calibration

Hardware: Pixhawk 6X Pro (Holybro)
Firmware: ArduPlane V4.6.2 (1ebd4d99)
Event: Hard fault occurred during compass calibration on the bench (no flight)

What happened

I was performing compass calibration on my Pixhawk 6X Pro when the autopilot rebooted unexpectedly. After reboot, the GCS shows the pre-arm message “Crash data detected”. I downloaded the crash_dump.bin file from the @SYS flash area via MAVFtp.

I was not able to identify the correct dataflash log for this session. Some logs on the SD card were being recorded without a valid date (showing 31-12-1979), and I could not determine which one, if any, corresponds to the crash event.
