Build failed! [RunAapt] ERROR: Error running AAPT

I am having the error specified in the title. I would appreciate any help. This is for a school activity.

What I already tried:

  • Removing the custom app icon
  • Deleting fonts and extensions
  • Also tried deleting Screen 2 and Screen 3, I still get the same error

The error:

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

Edit:
Well I found out MIT App Inventor is case sensitive because the issue was I had two assets with the same name. Thank you to Boban for pointing out what I had overlooked.

It seems that was just the issue. Thank you!
