Can't connect to STM32 using ST-LINK in Normal mode for debugging? I can connect with Hotplug? I can connect to the MCU under the setting using HOTPLUG why can't I connect using NORMAL I need to connect using normal so I can debug my program.

Normal Mode with Hardware Reset needs the nRST pin wired to the debug probe which you don't have.

The ST-LINK utility is superseeded by STM32CubeProgrammer software which comes with a nice User manual (UM2237)
