STM32H753 with "secure area": how to un-brick?

So I have a STM32H753 with active "secure area" - but the code in the secure area is buggy and hangs before jumping outside.

Is there a way to erase the MCU and recover, or it is bricked?

No RDP is set.

unfortunately, no tricks here, the MCU is bricked.

As secure area is define, jump in embedded bootloader not possible.

And debugger connection is not possible, while code execution in the secure area.
