I’ve experienced this issue and I’m pretty sure it has to do with PATTERNS assigned in the shape files not updating. I’ve actually gone thru this in Document Setup/References/ You go thru that list and you will find the PATTERN jpgs are red and need to be updated. I don’t recall which ones are doing this but if you click each one at a time and UPDATE there are a couple that will crash Layout. You actually have to fond those PATTERNS in your layout file and delete them from layout and purge them in Document Setup/References/ and there reassign them in the Shape Style side bar menu/tool. That has fixed it for me every time. It’s a pain n the ass but if your 20 sheets deep in a submittal set starting new is not an option. Hope this helps
