BOOTCAMP cannot locate disk!

So I have an iMac 2017 5k With a 2TB fusion drive, I Had windows 10 installed on my iMac and it was running really really well , until one day I decided to install Linux as a third operating system it caused some sort of boot problem , So i decied to format the whole drive using the Internet recovery method , which got me back to high Sierra the original os that came with 2017 imac and I understand that splits your fusion drive , so i I fixed that with a few commands in the recovery mode and reinstalled High Sierra on the fusion drive again as a single drive and upgraded back to catalina but the problem is After installing macOS Catalina I try to run Boot Camp and reinstall Windows 10 the first part runs Well on mac os but when it restarts i get this error “Boot Camp: Windows cannot locate the disk and partition specified”

i tried some Fix’s like reseting the smc and i dont have any external drives connected i repeated the whole process again erasing the bootcamp partition and reinstalling windows again i even downloaded a new iso but still nothing seems to be working please if anyone has a solution to this help me out i think it was caused by the linux installation it did something to the drive if yes how do i undo it
