Stuck at boot. APFS issue

Hello all,

I have tried to make a clean install of High sierra this time not using unibeast and multibeast. I have succeeded in installing the system up to the first actual and configuration of it but now I am stuck at boot with a weird error : handle_encryption_rolling:4061: er: request granted[0]

I supposed it is linked to APFS but I don't see how. And could not find any resources on IT yet.

For the record, I have
* Followed the guide for fresh install of High Sierra from Hackintosher not skipping the APFS conversing * started from a clean HFS partition. * I have the APFS.efi file at the right place in the EFI partition.

Any idea ? Or should I stick to an HFS partition ?

Thanks
