If you want to go to the spread, and if going there is causing a crash, try zooming in on a distant portion of the pasteboard where no page items are visible, then use either Layout>Go To Page, the scrollbars or the Page Up/Page Down buttons to get to the spread. When you arrive at the page, there should be no page items visible, so if that's what's causing your crash, you can select all and delete.
Might work…worth a try.
