Sequioa not installing

I followed the guide to download it and my mac is compatible for it on OpenCore yet I get the message after it downloads that “error while updating “ or something similar, my ssd also now says “MacOs - Data - Data - Data -Data” I’ve tried doing it like 4 times already and did PRAM reset and im not sure if I did it correctly but any advice would be appreciated
