Firmware upgrade for MPC-20 hangs

When attempting to upgrade the firmware for MPC-20 from v1.0.0 to v1.0.1 using a Windows 11 laptop, the upgrade tool gets to 5% in progress and then just hangs. After waiting 15 minutes, and restarting, the USB device is no longer recognized by the laptop. Previously it was recognized as DoriMidi usb device. The Upgrade tool can still connect by using the Virtual COM v1.5 driver and having the device in upgrade mode. However, re-attempting the firmware upgrade produces the same result.

If the device is not in upgrade mode, the USB driver is not recognized. As such, the Config Tool doesn't recognize a COM port it can connect to, and thus doesn't work.

How do I resolve this problem?
