Bootcamp installation on Big Sur 11.1

I have a MacBook Pro A1398. i7 2.5ghz, 500gb SSD, Big Sur V11.1 installed with all updates.

I’m attempting to bootcamp Windows 10 Home on a 128gb created partition on the main volume using Bootcamp assistant.

Downloaded Windows 10 iso from Microsoft website.

Used Bootcamp assistant to create bootcamp USB disk. Usb 16gb capacity formatted with MS-DOS file format (I did previously try exFat as well incase this was a factor).

Decrypted filevault prior to bootcamp. No firmware password on the machine.

BootCamp assistant creates Windows 10 boot usb and then progresses to partition wizard as normal; 128gb windows partition created, machine reboots (boot usb still in machine), but never boots into windows setup, always goes back into Mac Os, where the bootcamp assistant tells me I can remove the partition and start again if I wish, so stuck in a loop every time.

Checked on disk utility and bootcamp partition is showing with correct size, mounted, and 128gb NTFS partition. I don’t see the Bootcamp partition through the Startup disk option and pressing ALT on startup only gives me the MAC OS and I’m presuming the Windows USB boot device, which gives me the ‘non system disk’ error and to reboot.

I have read on similar articles even on this community that Big Sur has issues with installing Bootcamp, but have been unable to find one that specifically says that it never manages to get to Windows Setup. Is this something that Apple are still planning to address in an update or is there a workaround? Thanks in advance.

Diskutil list on my machine is as follows, and all looks normal as far as my knowledge goes:
