STM32L433RCT lock-up problem

[albfurkan]

Hello,
While rapidly powering the MCU on and off to simulate the vehicle’s internal power conditions, I have observed that the MCU occasionally ends up in this error state.
Has anyone experienced a similar issue or can provide insight into what might be causing this behavior and how it can be resolved?

If the power's been cycled, you'd expect the MCU to reset - so you'd expect it to go to the Reset Handler ?

Reset_Handler is the expected starting point of the application. There is no indication of an error here.

You can't maintain a debug connection while power cycling, so it's not exactly clear how you got into this state.
