Aero crashing in preview mode

Everytime I put my aero app into preview mode, the app glitches and crashes. I have only had this issue for the past week when I changed some of my assets, but the file size of these assets are rather small, and the larger ones have worked in the past. My phone is an iPhone 13 and I've owned it less than a year, so I don't think it's a phone issue causing this.
