Ubuntu 20.04 droplet won't boot - grub_calloc grub2 error

Tried to reboot my ubuntu 20.04 droplet to reset the root password, but it won’t boot - grub2 is stuck at

grub rescue>

When you try to load common or linux.mod (or any consequential modules, the ones that give you the kernel command), I get the error -

error: symbol grub_calloc not found

I could fix this on a VM of my own, or anything I could attach USB media to, but IDK what to do on this droplet…
