I had the same problem. When I tried to program using VSCode + PlatformIO, it didn't accept programming, it gave me a flash size error, I got another prototyping board with the same processor and programmed it. I went back to the board, tried to reset the flash, but without success. After many attempts, I managed to program, then after some programming the defect returned, I tried to do the same procedure and I can't program anymore. The cable is fine because I have serial communication with the PC. I've already updated the driver and it didn't work.
