I’ve found above yaml error in your SDKM log.
Please check if Use sdkmanager to flash the jetson orin nx failed - #27 by fschiffel could help in your case.

Are you using a fused board? (i.e. is the secureboot enabled in your case?)
If so, you have to specify -u and -v options in flash command.

Please try using the following command instead.

$ sudo ./flash.sh jetson-agx-xavier-devkit mmcblk0p1
