STM32cubeIDE 1.19 Debug Error : Unable to get core ID; No STM32 target found

[KiYoonLEE]

Hi, I have an Error when using Debug in STM32cubeIDE.

ST-Link Server is running on port : 7184

ST-LINK SN : 410035000C000032484C4D4E

ST-LINK FW : V2J46S7

Board : --

Voltage : 3.24V

Error: Unable to get core ID

Error: No STM32 target found! If your product embeds Debug Authentication, please perform a discovery using Debug Authentication

Encountered Error when opening C:\ST\STM32CubeIDE_1.19.0\STM32CubeIDE\plugins\com.st.stm32cube.ide.mcu.externaltools.cubeprogrammer.win32_2.2.200.202503041107\tools\bin\STM32_Programmer_CLI.exe

Error in STM32CubeProgrammer

Shutting down...

Exit.

The error says that Connection is not completed, But Window terminal I can see that PC recognizes ST link and MCU. 

I did 1) hardware under reset (debug configuration)

2) check hardware connection if it is proper

3) update ST link firmware, driver version

But Still I have a same error and then I cannot debug using ST link... If you guys know solution Please help me.
