Bug/Issue Chest bug XB1

I need help fixing a chest that's been glitched out for a long time now, I have been pretty bummed about playing the game since but finally got around to posting about it.

Normally I would just restart but this is a very big save. I hope you guys can clear this up for me.

Details about the bug is that the chest is in-accessible. When first loaded, the chest inside the house seems to change graphics of house furnishings at a rapid pace then stop at the chest graphic. Can't open it.

Sorry, here's hoping you can help me.

 

gov shut down effect forums too?
