My World loads but crashes the game as soon as I open inventory.

The world has been working fine since I created it but for some reason this morning it wont stop crashing. I do have a few add-ons but they are all Marketplace add-ons. I did try one of my other worlds and I noticed its having me re download all my packs again. The next world loaded but the textures didn't. I had done nothing different from last night such as add more add-ons or adjust settings.
