While cleaning up fonts on the Efi partition to resolve failing bios updates, I realized that the fonts do need to be restored. Otherwise, there were issues such as the BitLocker screen which prompts you for your password (and presumably other preboot screens) being blank. I assume this happened since the .ttf files needed for their rendering are now gone.
If this happens, repair the EFI bootloader by using the following commands:
# mounts the system partition so we can access its contents
mountvol y: /s
# switch to the partition
Y:
# see the above link for an explanation of this command
bcdboot C:\Windows /l en-us /s y: /f UEFIThen restart the machine to verify the changes took effect.
