This Kernel panic is a known bug of the closed source MediaTek WiFi driver. Now we know it can not manage if there is a WiFi AP in the neighborhood with some Unicode character in its SSID.
Onion @administrators deeply kept silent about this bug.
It seems Onion's new WARP CORE driver (also closed source ???) can manage this situation.
Unfortunately Onion @administrators do not say too much about this bug feature (as usual ;-).
@György-Farkas kernel was corrupted for sure, that's something I can tell you with honesty. The device was literally dead, only after inserting a microSD card with a new firmware my device was able to update itself and become functional.
Well... no one but you should know if this correct (or not ;-)
