Hello, I've been having an ongoing issue with booting up Oracle Database App Development VM in VirtualBox Version 6.0.22 with a Windows 10 host.
After starting the VM, startup ends with a black screen and no prompts. I'm attaching log file. Does anyone have any advice or suggestions? TIA.

I see a booting guest OS and loading of Guest Additions. It looks like Virtualbox is working. Try pretending the OS is installed on a real PC and troubleshoot the OS directly.
