Getting same issue, when doing a fresh save, playing for a bit is a follows;
- asking to select options for difficulty and pc specs is untranslated
+ Nami's dialogue before battle is translated
- Nami's dialogue in battle as well as options are not translated. that's as far as I got before closing the game and waiting for info.
thing to note; I have both demo and main game. the demo's patch does work (which uses .NET version 6.0). Main Game's does not (Which requires .NET 7.0)
When I tried to patch the main game and it directed me to a link for .NET 7 which failed to work properly (I had to grab the windows sdk installer myself for it to work)
Not an expert on how anything about this patch or .NET actually works, but maybe it has something to do with the differences between .NET's 6 and 7 versions and codebase (just my shot in the dark)
