OpenCR 1.0 Board malfunction depending on the uploaded code

hello everyone;
I currently have an OpenCR1.0 card.
I’m trying to program this board with the Arduino IDE. But I’m facing an interesting problem.
-If I load any of the DynamixelWorkbench examples, there is no problem, but if I load a code I created myself —OpenCR1.0 is no longer recognized by the Arduino ide and I get the following errors.
Fail to open port 1 : COM32
Fail to jump to boot
If I put the OpenCR card into Recovery mode (Sw2 + Reset button) and load any of the Dynamixelworkbench examples. It doesn’t error anymore. But until I try to load the sample code I created again.
Why could this code cause this error?

#include <DynamixelWorkbench.h>

#if defined(__OPENCM904__)
#define DEVICE_NAME "3"  // Dynamixel on Serial3(USART3)  <- OpenCM 485EXP
#elif defined(__OPENCR__)

#endif

  // Set new goal positions for the servos (you can modify these values)

}

Not:I would like to give additional information that may be useful for a better understanding of the problem:
-This problem especially occurs when you load Dynamixel related samples. In general, the codes installed for Dynamixel sometimes work and sometimes cause such problems.
-One more additional information: If this dynamixel-related code is installed on the card, when I give additional power to the card (from the SMPS port) and plug the USB port into the computer, the computer does not detect the USB port. But if I remove the power from the SMPS port and plug in the USB, the computer detects a USB port, but the code still cannot be loaded. .

Does anyone know the cause of this problem?
