for some reason after I executed this I wasn't able to connect again to my device, getting error "Can not connect to target."

I found a JLink incantation that works! After setting the appropriate NRF_POWER->RESET register to enable pin resetting, it next switches the Segger device into JTAG mode and directly manipulates the SWDIO (i.e. TMS) / SWDCLK (i.e. TCK) level to achieve the reset. This provides a pin reset, which provides a hard reset and does not re-engage the debugger mode.

si 0
tck0
t0
sleep 10
t1
exit

Tested and working for me!
