Upload to Gallery immediately crashes my game..

Hi all. I'm after some advice. I regularly upload lots to the Gallery and haven't had an issue until the last couple of months. I can save my lots to my library with no issue and download/place lots from the gallery, but the last two lots I have tried to share to the Gallery, it has immediately shut off my game back to the EA app. I can save the same two lots to my library absolutely fine, but it's the second I click to "share" it immediately crashes the game (I also don't experience crashing in build/live mode)

The crash .txt file is very short, but I can never make sense of those. All of my mods are up to date, graphics drivers up to date etc. and this issue has only started happening recently. 

Any ideas?
