Opus Quad (FW v1.22) fails to Power Off after Internal Recording (Power Button unresponsive)

Bug Report: Opus Quad (FW v1.22) fails to Power Off after Internal Recording (Power Button unresponsive)

Device Information:

Model: Pioneer DJ Opus Quad

Condition: Brand new unit, purchased ~1 month ago.

Firmware: v1.22 (Latest)

Storage Media: Samsung T9 SSD (exFAT), connected via USB-A.

Description of the Issue: I am reporting a critical firmware bug regarding the Power Management system on a brand new unit.

After recording a DJ set (approx. 1 hour) to an external SSD using the Internal Record function, the unit refuses to power down.

Steps to reproduce:

Record a set (~60 min) to a high-speed SSD (Samsung T9).

Stop recording.

Successfully perform "Software Eject" on the SSD via the screen.

Attempt to turn off the unit using the physical Power button.

Symptoms:

The unit ignores the physical Power button completely.

Crucial detail: The system is NOT frozen. The screen works, I can load tracks, play music, insert new USBs, and navigate the UI perfectly fine. The OS is fully active, but the Power Management interrupt seems disabled.

Holding the Power button for a Force Shutdown (Hard Reset) for 30+ seconds does nothing.

The only way to shut down is to physically pull the power plug (AC mains).

Troubleshooting already attempted (failed):

Updated to latest Firmware v1.22.

Tried restarting a dummy recording to clear I/O buffers.

Tried switching Input Sources to reset audio routing.

Tried holding the Power button for extended periods.

Since the unit is only 1 month old, this is clearly not a hardware switch failure, but a firmware bug where the recording process does not correctly release the Power Management handler.

Please investigate this for the next firmware update.
