The table says module 144 = EC(Shop) but don't ask me what that means. I don't think it has something to do with ElectronicCash even if it's related to the shop.
Here might be a fix for you:

"I fixed it. Seems it wasn't a HBL or libnx error. My SD card managed to only mount itself in read-only which caused some errors with libnx, causing the error code. (It was hidden at first, since games from the sd still seemed to run with no error.) After reformatting, the sd card seemed to work again and no errors."
