Upload fails in Platformio and ST-Util

[IerwinDE]

Hello,

I'm trying to flash my Sideboard that is equipped with a GD32F130-C8T6. After I realized that the programmig pins are in a different order than in the description I have successfully unlocked the chip. There was an error saying Option Bytes could not be set but since the same error is shown in the video that is linked in the redme I guess thats ok. When I try to upload with PlatformIO I am getting an error after the compilation. I have very little knowledge of PlatformIO or Visual Studio but the message seems to suggest that its not finding the conected device and insteag looks for a remote agent to perform the flashing:

I also tried to flash the firmware.bin from platformio via ST-Link and get an error message:
