Yes, syntax is wrong for HAL_UART_Transmit(), it wants a POINTER, and will send a pair of raw bytes over the wire. Will look like random junk bytes in a terminal application.
HAL_UART_Transmit(&huart1, (uint8_t *)&readValue, sizeof(readValue), 100);
for human readable numbers
char string[10];
HAL_UART_Transmit(&huart1, (uint8_t *)string, sprintf(string, "%d\n", readValue), 100);

"The Problem" is ill defined.
No idea what board or chip you are using.
No idea how and to what the UART is configured and connected.
No idea what terminal app you have connected, what you are seeing, or what you expect to see.

Try paste here red console log complete not as screenshot. Seems error on board connection....

I use stm32G01291 and CubeIDE
Actually I am a data scientist and just want to get data from ADC and transmit it to python in order to some analysis and ML algorithms!
I used for configuration like this:
ADC1 - IN9 (tick)
Parameter Settings --> ADC Settings --> Continuous Conversion Mode (Enabled)
Enable USART1 asynchronous
Parameter Settings --> Basic Parameters --> Baud rate 9600

Actually codes work now I can see the readValue in live Expression but I am not sure that I can get from serial on the python too! do you think is it enough writing code
for USRAT1 transmit by USB?

Seems you are on linux and OCD. For UART to USB you need VCP ...
Too stm32G01291 dont exist
Start any request here with board name or custom.

Thanks again for the reply!
I solved the problem it was related to debugging. I use macOS.
