Issue Uploading Firmware to KC868-A16 Rev:1.6 - Error 2-Sync Fail

I haven’t installed the RF 433M receiver. Could it possibly be related to the USB driver? I installed the one provided in the link and also tried the latest version from the chip manufacturer's website, but unfortunately, it had no effect. I used UartAssist to try connecting, and I was able to open the connection. However, after disconnecting, I'm unable to connect again. I have to power off the KC868, switch to a different USB port, and power it back on, then I can open a new connection in UartAssist. Most of the time, when I try to install the firmware, nothing happens, as you can see in the screenshot below.
