I just checked and pkg viewer did the same thing to me. instant error, so I think it needs to be updated. using pub chk you can check integrity without that problem:
passcode is all 0s as I mentioned. pkg viewer hasn't been updated since 2018, so that may be the reason we're having a problem with it. reading the content of a pkg also doesn't work for me if the firmware is above 5.05.
