Kernel Panic : CPU7 failed to shut down

I have a MBP M2 2023.

I have the repeating following Kernel Panic as provided here :

I've already sent the Mac to an Apple Store, that restored the computer. After restoration, all seemed normal, but as I've reinstalled some apps and peripherals, the error keeps happening.

Does anyone have an idea on how I could find what's causing this ? I unplug peripherals and uninstall some apps and it seems to go away, but then reappears, and I'm kinda lost and don't wanna go back to the Apple Store.

The current list of plugged peripherals are :

• External display via HDMI cable,
• Android phone via USB-C cable
• External speakers
