I found some related topics but they were about AAPT errors. I am finding this error. I've already attached blocks image and error file both. Can anyone help me with this?

App Inventor is unable to compile this project.
The compiler error output was

The error log is complaining about your icon.

Remove it and see if it will build.

Edit:- I changed my image from jpeg to png & now its working...Don't know why app inventor is doing these things....Looks like I need to shift to kodular....If anyone knows why this happens, do tell?

I've proposed an alternative in another topic.
