I've been following this guide for two years now, without any problem.
I did a silly thing yesterday and I can't boot anymore my hack (just from an USB stick with an install for Mojave).
I was using two NVMe one with Mojave 10.14.6 and the other with Catalina 10.15.4, both of them perfectly functional with Clover.
I tried your Open Core on my NVMe with Catalina (just changing my serial… via Xcode), I made something wrong and now I can't boot anymore, even on my NVMe with Mojave.
I erased the OC folder from EFI partition of my Catalina NVMe and replaced it with a clone of the EFI folder of my bootable USB stick via terminal (dd if=/dev/diskxxx of=/dev/diskyyy).
The EFI partition looks OK with Terminal but I don't know what I could do know ?
There's no need to use "dd" to clone the EFI partition. You can just drag 'n drop the EFI folder and "replace".
Please try clearing NVRAM by pressing F11 at the Clover boot menu and see if you can boot from internal drive again.
