Drive gets corrupted when I install Sonoma and doesn't read all my partitions.

So, I have a Late-2014 iMac with a 1.12TB Fusion Drive. Sonoma runs perfectly after running OCPL on my drive and installing kexts. I tried installing windows with another partition. But when I got to the USB install Windows setup said it couldn't read or partition on the chosen drive (partition). Also disk utility thinks my drive is 2TB when I try to partition in disk utility, But also sees it 1.12TB everywhere else. Then it wouldn't read the partition that I made in disk utility and refused to read it. When I tried to run recovery for the Drive it said it was corrupted and that I needed to boot into recovery. I had to go back to macOS Big Sur after that. I already made a windows partition in Big Sur and want to try installing Sonoma again. Is there anyway to fix my drive in Sonoma if I do plan on reinstalling it?
