Can you use the dblk shell command on the partition that is expected to contain a FAT32 file system? Please attach output from dblk of the first block of the partition to the BZ. It should indicate a FAT32 file system.
Can you also try using efifmt from the EFI Disk Utilities to format the partition and see if you get a different result? https://www.intel.com/content/www/us/en/download/714351/uefi-shell-disk-utilities.html#:~:text=The%20EFI%20Disk%20Utilities%20contain,follows%20the%20UEFI%20Specification%202.3.
