I think this is an operating system issue. The line "mount: /var/lib/grub/esp: unknown filesystem type 'linux_raid_member'." says that there is some basic issue with the file system. Similar reports can be seen across the internet, e.g. Upgrading from Ubuntu 21.10 to Ubuntu 22.04. It's probably best to ask the question on Unix & Linux Stack Exchange.
