Thank you for your kind response.
I’m aware that the configuration in question was incorrect, but at the time, I didn’t know the root cause of the upload issue, so I was changing various settings and happened to take that screenshot during the process.
Fortunately, with help from @ptillisch, I was able to resolve the issue and successfully upload the code.
However, I have an additional question: I would like to upload code to the STM32F103C8T6 (Black Pill) via a USB cable, but it currently doesn’t seem possible.
