Cooker no longer boots to GUI after update

Whatever else updated with Firefox this morning, now caused two of the Cooker VirtualBoxes to no longer boot up to a GUI. The only one I can use is the one not updated.

Booted into runlevel 3, ran dnf, no updates. X does not start.

Attached screenshot was taken with my mobile.


EDIT: Turned on 3D Acceleration in the VirtualBoxes and it successfully booted to the GUI login (graphical desktop managers).
