pop boots to busybox, but no keyboard response - fixed

i have auto updates on and yesterday, pop shop told me to restart. in hindsight it was a bit weird, i just had another restart to update a few days ago, and i think the restart message on the window was in orange, but this last time it was black. since this restart, the system goes to busybox, and while the keyboard lights up, it doesn't react to any input, not evem caps lock switchingwith a live usb, i checked the efi and the root partition, via disks, both seems to check outi also have a mint install on the same ssd, and that works just finealso windows on a different ssd, i haven't tried iti have tried the guide on system76's page, to repair the bootloader, didn't seem to have any effectwhat could be causing this and how can fix this?edit: typos
