stm32l562e-dk board can not be connected by stm32cubeprogrammer after setting nSWBOOT0 to 0 when TZEN=1

I get a stm32l562e-dk board, when I use the following figure setting to connect to the board and modify nSWBOOT0 bit to 0(TZEN=1). I found that I can not connect to the board using "Hot plug" or "Normal" mode.

whether I FOREVER lost the device?  In addition, I also make a "mass erase" operation using stm32cubeprogammer when TZEN=0.

If no lost the device, how to restore connection to the board and adjust the setting in option byte?

BTW,  I get  the following connection prompt when connecting to PC usb port.
