[jacobkeeler]

Bug Report

A crash can occur during the shutdown process if IGNITION_OFF is sent during video streaming, specifically if the video streaming app is included in a previous PTU.

Reproduction Steps

1. Connect navigation app
2. Perform PTU which includes connected navigation app
3. Activate navigation app and start video streaming
4. Send IGNITION_OFF from HMI when video streaming starts

Expected Behavior

Core shuts down normally

Observed Behavior

SIGSEGV occurs during shutdown
