VirtualBox startup error NS_ERROR_FAILURE (0x80004005)


detail forgot the screenshot, the specific error message is NS_ERROR_FAILURE (0x80004005)
Causes:
(personally) During code debugging, for some reason the project’s log files filled disk C (my native Shared folder with vm was on disk C, crying… If you are using Windows, put the Shared folder on another disk), the virtual machine automatically pauses, and the forced exit occurs. After two forced exits, the 0x80004005 error occurs.
Solutions:

find your virtualbox, or virtualbox shortcut on the desktop, right-click – > Property – & gt;
after modification, open VirtualBox again, error message is as follows:
the Document is empty.
Location: “C:/Users/Administrator /./VirtualBox VirtualBox. XML ‘. The line 1 (0), column 1
