Trevor.
I ran into this same issue tonight. Do this.

Select your menus, and save them as templates.

Start a brand new project.

Import the most important (largest) file first. (IMPORT ONLY FROM PROJECT PANEL! AKA, Import As…, etc)

(Thru this process, I did check project after EVERYTHING I did to see if there was something making the thing crash)

Menus you saved (Do the Import as Menus, and your menus will show up in the Encore format (Don’t do the photoshop))

Continue the process of rebuilding until you get what you had before (along the way using check project)

This should work! Let me know if you need anything else and I’ll be glad to help.

I’m having the exact same issue. Been working on a project for 20 months, got to this stage, and now it won’t build. Talk about anti-climatic!
