2017 F56S, stock excepting a few recent BimmerCode tweaks to lighting.

Today while I had the car running, the iDrive did a spontaneous reboot. Was sitting in a parking lot and it was streaming audio via Bluetooth, and I had the MINIMALISM fish up on the display. All of a sudden I got a buzzing sound instead of music, and being unable to mute it (that didn't work) or anything else (iDrive unresponsive, and ultimately screen turned off), I killed the engine. Then, before I could start the engine again, the iDrive rebooted (startup splash came up).

This happened to me once before, months ago, before I even had a copy of BimmerCode to fiddle with; so BimmerCode tweaks aren't what did this.

Just curious as to whether anyone has heard of this and/or had it happen to them before? Any concerns? Software being what it is, I'm not worried, but definitely curious.
