Did you try to rename your LO directory profile? (see https://wiki.documentfoundation.org/UserProfile#Windows) Please attach or give a link to one of the files so we can give a try. (have in mind that any of attachment is automatically made public) If you can't, you can try to retrieve a backtrace (see https://wiki.documentfoundation.org/QA/BugReport/Debug_Information#Windows:_How_to_get_a_backtrace)
