Hyrule Warriors - Error ERREULA-102-1020. Can’t get past it. Cemu

In Hyrule Warriors on Cemu, when I beat a level it gives me this Error erreula 102-1020. I can’t get past it. I was able to just restart and it would save but now when I get to dark mountain and skyloft and beat it, it says new historical entry, and then the erreula 102-1020 comes up and I can’t get past it. Any ideas?

thanks
