It looks like it crashed on the keyboard thread after the keyboard device (Majestouch Convertible 2) was added back.

The keyboard was removed at 11:28:38 but added back at 11:59:24. I can only assume that the keyboard got removed after some idle period within the VM. How is the keyboard connected to the host and/or guest? Is it via Bluetooth or USB? You could try turning off power management of USB/Bluetooth device at the Windows 10 power settings in the VM first. I don't use an external keyboard with my MacBook Pro so I don't see any USB power saving settings but you could also look at that the macOS level to prevent disconnection/power saving after some idle period.
