Pretendo Network in an incorrect state
Sometimes when switching to Pretendo, it doesn't fully switch your account to the Pretendo Network leaving you in an incorrect state between networks. Another way to cause this is to load the HOME menu without loading external FIRMs and modules enabled, which may happen accidently if Luma is updated and its config resets without you turning it back on. Even after turning loading external FIRMs and modules back on your console will continue to be in an incorrect state. Being in this state will cause different errors than usual.
The easiest way to tell if you are in an incorrect state is to look at your badges on the HOME menu. Normaly when you switch to Pretendo Network your badges will disappear; if your badges don't disappear then you haven't correctly switched. Another way to tell is to look at NNID settings in System Settings, if it gives you an error and then displays your NNID profile rather than your PNID/initial account setup then it hasn't correctly switched.
To fix being in this state, open Nimbus and select Nintendo. Reboot your console then open Nimbus again and select Pretendo. This may take a few tries.
