Can't Open Virtual Box After a Crash

[Colin Smith]

-I am using version 6 of Virtual Box, and have not installed any guest additions
-Host: Mac OSx version 10.14.4 256GB of memory, Guest: Windows 10 64-bit 70GB of memory allocatedDocument is empty.
-This is the error message I receive upon opening VirtualBox:

Document is empty.
Location: '/Users/Colin/Library/VirtualBox/VirtualBox.xml', line 1 (0), column 1.
/Users/vbox/tinderbox/6.0-mac-rel/src/VBox/Main/src-server/VirtualBoxImpl.cpp[624] (nsresult VirtualBox::init()).
Result Code:
NS_ERROR_FAILURE (0x80004005)
Component:
VirtualBoxWrap
Interface:
IVirtualBox {d0a0163f-e254-4e5b-a1f2-011cf991c38d}
Callee:
IVirtualBoxClient {d2937a8e-cb8d-4382-90ba-b7da78a74573}

I am not sure what to do at this point, but I will be trying to find the file referred to in the error message. I am hoping for a solution beyond having to wipe everything and start over.

If you look in the directory /Users/Colin/Library/VirtualBox you should see that there is another file called VirtualBox.xml-prev. Provided this file isn't also 0 bytes in length then shutdown everything VirtualBox related, and make a copy of VirtualBox.xml-prev as VirtualBox.xml to replace the damaged copy.

Fire up VirtualBox and all should be OK.
