The error message mentions the Project icon (which should ordinarily be a png or jpg image 48x48 or 96x96 pixels in size). If you changed the default icon and the replacement icon you use is larger than 96x96
, your app will crash
So, without seeing all your blocks, a very astute guess is the icon is the issue based on the error message you posted.
Why not just shrink your existing icon as recommended by Taifun or revert to the default icon and try running the Project? If it runs (and certainly it has a great chance of running), your problem is solved. If not, something else is wrong in addition to using a large App icon.
