Target connection fails with "Cannot identify target as a stm32x" (although STM32L053 works)
First, update the SW4STM32 software with the menu Help => Check For Updates
You are in v1.8.0 from install, please, update the plugins to v1.11.0 (as of today).
The openocd tells you that the voltage is around 0 volts so i suspect you didn't connect the VDD of the STM32 to the input of STLink.
Also, did you connect the RST line output of STLink to Nrst of STM32 ?
