Unable to Enter Desktop Environment on Fefora Rawhide

After booting, when I try to login into a desktop, it seems that the Xorg server crashes and simply returns to the login screen. Examining dmesg indicates a deadlock with the Guest Additions video driver.
VirtualBox 6.0.6 r130049
Host: Windows 10, Guest is Fedora Rawhide x64 with 8 GB of RAM and with Guest Additions installed.

VBox.log attached.

At the moment< I do not know how to extract my VM's dmesg.

Switch from "VBoxSVGA" to either "VBoxVGA" or "VMSVGA". The "VBoxSVGA" is the default for Windows guests, not Linux guests.

I've seen that in the past. If there's a "cog" under your login name, try the "Gnome classic", if such an option exists. Otherwise, try without 3D acceleration, and update the Guest Additions.

What are the technical differences between VBoxSVGA, VBoxVGA, and VMSVGA. If that is covered in the user's guide, I don't have convenient access to it.

The "technical differences" between them? I don't have the slightest idea! Seriously, why do you care? They're virtual GPUs, and what I do know is in the User Manual, ch. 3.6.1 Screen Tab.

Other than that, you could study the source code...
