Please zip logs in future.

What's with the strange log file location? Is this using Vagrant, Portable VirtualBox, anything like that?

5.0.40? It seems long past time to update VirtualBox. Support for the 5.0 branch ended two years ago.

I'm not altogether sure what the above means. I assume it means that some piece of code or data in memory is not the expected size. You could start by checking the certification on this DLL yourself. Also run "sfc /scannow". And update VirtualBox.
