Picker not shown

I've got a complete working installation of MacOS Ventura on OC 0.9.8, but the Picker does not show when booting. Picker was shown before install, but has since disappeared. I've tried enabling/disabling/removing/updating Opencanopy , fresh rebuild of EFI in OC 0.9.7 and 0.9.8, set PickerVariant to Builtin/Auto, changed show/hide picker, changed timeout, EFI on thumb drive/SSD, all with no luck. When Opencanopy is enabled, I receive

OCUI:Failed to load images
OC: External interface failure, fallback to builtin- Unsupported

Then black screen with functioning picker

With Opencanopy disabled, I still get a black screen with a functioning picker.
