The main reason for the occurrence of this error is the presence of an older version of prod keys in your device. Ryujinx releases new versions of keys over time, and you are required to update them regularly.

But if you leave them alone, compatibility problems can emerge. This explains why parsing errors occur and you are unable to install the most recent firmware using older prod key versions.
