I can’t open anything, no page, no new window—nothing in Konqueror. All the options for selecting any item in the menu bar are greyed out. It asks the question open konq:blank
whenever I open konqueror. I have attached the screenshots of what I see.

When I launch konqueror
from the command line, I get the following messages.
