Having an issue flashing my 0x64. Invalid literal for int() with base 16

[3BeetMassacre]

First, I apologize for posting in the General forum but couldn't find the Ox64 section.

Any ideas on how to remedy this?

Win 10 pro
Dev Cube 1.8.3
Using firmware dated 2 weeks ago
Silicon Labs CP2104 USB to UART Bridge
Following the instructions on the Github page found HERE

Dev Cube MCU page flashing m0 and d0 was successful but then moved to the IOT tab of Dev Cube in order to flash the BL808-firmware.bin to address 0x800000 and received the following error:
