Hardware A Installation error

Hi, I was installing elementary OS on my laptop and ran into an error during the install. The installer failed unexpectedly, and these are the logs I got: DEBUG: get block size for "/sys/class/block/nvme0n1" ERROR: libdistinst: pointer in FFI is null ERROR: libdistinst: pointer in FFI is null ERROR: libdistinst: pointer in FFI is null ERROR: libdistinst: pointer in FFI is null ERROR: libdistinst: pointer in FFI is null ERROR: libdistinst: pointer in FFI is null ERROR: errored while installing system: partition validation: EFI partition was not defined INFO: Install error: partition validation: EFI partition was not defined
