After mission crash and no input bug

Xbox One

About to begin a 3rd play through. This is the second time after completing a nest/lair/citadel and game crashes after ‘mission accomplished’ message. It shows xp sheet, and attempts to load geoscape, and crashes to dashboard. I saved after defeating spawnery and reloaded, and now game is stuck on load screen.

In addition, every few missions, some missions don’t allow any confirmation button inputs, nor allows navigation of start menu to restart or reload. Any update on the issues stated?

I have seen several threads on the matter and no solid solutions. Please help
