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](https://forums.developer.nvidia.com/t/use-sdkmanager-to-flash-the-jetson-orin-nx-failed/310757/27) 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.

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

```
