Yocto dosdcard.sh fails after Pre-processing mb2bct config. Command dtc

I keep getting a strange crash error trying to flash a yocto image onto a sdcard. I am following the ridgerun instruction with dosdcard.sh. Here is the error.

If anyone has seen it, I sure can use some help today. I am on a Ubuntu 20.04 pc.

command prompt:/tmp/tmp.uDX0GcD6hR$ sudo ./dosdcard.sh /dev/mmcblk0
