this is the page im getting the problem, the error is probably something with the onSaveImageAsync function.
I couldnt get chatgpt to find the problem

the message i get when i try to save is
[Error: Failed to snapshot view tag 14]

i tried asking chatgpt and claudia but they couldnt help,

this code is also the original tutorial code from
https://docs.expo.dev/tutorial/screenshot/
