Crashing every time in the SSBU

[NathanMint]

Every time I start up SSBU it works fine then after a bit, the game freezes. No text or anything and I have to quit the game and restart to get it to work, but then it will crash again sometime anyway. I tried disabling all mods, but that didn't help. It can freeze in the main menu, character select or map select. I have updated ARCropolis to the latest version. I only have 2 mods installed. Training mod and Chaos mod and 2 skin changes. Also the training mod doesn't show up. Not sure if that's a problem or not. Thanks for reading this.
