That warning doesn't matter, it's for kexts patches. You've clearly not installed that file, that's all. Did you nevertheless manage to boot?
If not, didn't this issue happen after that you installed a High Sierra update? If so, it's highly likely that you're back with Core Storage applied and Enoch does not support that. You'd therefore have to boot with Clover (i.e. your original HiSie USB installer I presume) and revert the partition to plain old HFS+ before Enoch can boot High Sierra again.
