mojave bootcamp fusion update issue

Hi, I hope someone out there can help me. I want to create a bootcamp partition of windows and I seem to run into road blocks every way I try to do it. I have a 2017 27 inch iMac with a fusion drive.

I did have Catalina installed but I got rid of that. In the process of installing high Sierra I somehow split my fusion drive.

I put my fusion drive together again and then upgraded to Mojave hoping to install the update for bootcamp on fusion drives.

When I run it I get this

I have no idea why this update won't install. Any help would be so appreciated. Here is what disk utility sees and my diskutill list too if that helps.

iMac 27″ 5K, macOS 10.14

There are two different updates, depending on your macOS version.

macOS Catalina should be updated to 10.15.5.

Thank you for this. I did manage to get bootcamp to install in the end. However once it restarted the screen went black. I've seen other people post about this so I'm really hoping if I connect a second monitor I will be able to fix this problem. Just have to order a hdmi adapter to do so. Very frustrating process.
