If this is your current partition layout, run
diskutil eraseVolume jhfs+ BC1 disk0s3
diskutil eraseVolume jhfs+ BC2 disk0s4
diskutil mergePartitions jhfs+ BCMP disk0s3 disk0s4
If you these commands complete without any errors, then
diskutil eraseVolume fat32 BOOTCAMP disk0s3
and now run BCA and click on Remove/Restore.
Once you have your full disk space in macOS, re-run BCA and try to install Windows. You can skip the Create+Download steps.
