These crashes come from Windows/.NET and are not caught/processed by Logos. I do wish/humbly suggest that Logos wraps their I/O and system calls in try/catch blocks so something a little more elegant can be done with these instead of bombing the user out when something fairly typical inside of Windows happens.
