UREGENT: Multitech MDot: Flashing MDot firmware compiled using MBED Online compiler causes CRC Errors

I am building my application using the MBED online compiler and we have always been able to flash the firmware without any issues however as of today and I am getting CRC errors as shown below, when flashing the MDot module using tera term and ymodem interface. I am using the MDot library 3.1.0 and mbed-os-5.7.7 to compile my custom firmware. We are blocked on generating production builds and would like to receive some assistance ASAP.

bootloader :> upgrade ymodem
[INFO] Starting upgrade
[INFO] Starting YMODEM file transfer
[INFO] YMODEM file transfer succeeded
[INFO] appended crc: 50050000
[INFO] calculated crc: 2793190355
[ERROR] File validation failed

Thanks,
