Hi
I’m not sure the above is an indication of something wrong with snack, (although there is currently a problem with images not showing on mobile).
If I create a new snack and load it on my phone it works fine except for the image problem mentioned above.
I have seen the expo app crash for seemingly simple things like specifying padding: '8px' instead of padding: 8, so your crash might be something like that.
Did you make any changes at all between when it was working and when it wasn’t?
If you create a new snack, does it crash?
If you export your snack and try using expo start locally does it work/crash?
