Critical Error on rebooting Win10 guest

[reggler]

Hi I'm running the pre-release version Version 6.0.13 r133688 and got the linked logs & attached VBox.png when I attempted to reboot my Windows 10 guest
VBox.log: https://file.io/mK1GJe
VBox.log.1 https://file.io/XwRgWT
VBox.log.2 https://file.io/ZJbBev
VBox.log.3 https://file.io/fYhD1u

We need to see a complete VBox.log, from a complete VM run, where the problem occurs, not 4 different logs, hosted on a 3rd party server:

• Start the VM from cold-boot (not from a paused or saved state) / Observe or recreate the problem / Shutdown the VM (force close it if you have to).
• With the VM completely shut down (not paused or saved), right-click on the VM in the VirtualBox Manager and select "Show Log".
• Save only the first "VBox.log", ZIP it and attach it to your response.

There's no need to include "VBox.log.1", "VBox.log.2", or "VBox.log.3". Neither a black screen is that helpful...
