STM32CubeIDE v 1.19.0 log redirection on uart in BLE application of STM32WB05KZ Problem

[atuls2004]

I am working on custom evk of STM32WB05KZ sdk(stm32cubewb0-v1-3-0) on STM32CubeIDE_v_1.19.0 and STM32CubeProgrammer and trying to redirect logs on UART1 through __io_putchar/_write. It is working with Examples(GPIO_EXT, I2C, ADC, etc) but while running BLE(Any of it) section from Applications it is not giving any log through UART/Virtual COM Port. Below is the refrenced code of my main.c:
