This starting value is from an old partition utility and is often incompatible with grub2, and leads to embedding problems which is one of the errors you're having.

Duplicate PV UUID is a problem. What do you get for pvscan?

You have some mutually incompatible factors: LVM + RAID + a first partition that starts on LBA 63. So at least one of those needs to be altered. I'd say backup whatever you need to keep and obliterate the installation by completely removing all partitions. It's easiest done with the installer's Automatic/guided partitioning by reclaiming space, and choosing the Delete All option; or in Manual/custom partitioning by deleting all existing LVs and partitions.

No. Hardware raid will show up as a single /dev/sdX device. What results do you get for lsblk?
