I just installed VirtualBox 6.0 today, and none of my VMs would open up.
Failed to open a session for the virtual machine Windows10.
The virtual machine 'Windows10' has terminated unexpectedly during startup with exit code 1 (0x1).
Result Code: NS_ERROR_FAILURE (0x80004005)
Component: MachineWrap
Interface: IMachine {5047460a-265d-4538-b23e-ddba5fb84976}
Edit: changed it to a VM that’s in my internal drive
