Serial monitor not working on CH34x driver

I am trying to read the output of the serial monitor but the only thing that shows up is the following:

Executing task: C:\Users\Dominik.platformio\penv\Scripts\platformio.exe device monitor <
— Available filters and text transformations: colorize, debug, default, direct, esp32_exception_decoder, hexlify, log2file, nocontrol, printable, send_on_enter, time
— More details at Redirecting...
— Miniterm on COM6 115200,8,N,1 —
— Quit: Ctrl+C | Menu: Ctrl+T | Help: Ctrl+T followed by Ctrl+H —

I installed the CH34x driver to program the ESP32-Cam-mb with VS Code & PlatformIO. This works fine and the code is uploaded. The baud rate is set up correctly. However there is no output.
I also used to Arduino IDE and the serial monitor works as expected there.
