Help! I can't compile my app - AAPT execution failed

Hiii, I'm trying to create an app to do notes with a unit converter, but while I was doing a section named configuration and try to compile the program, I can't do it.

This is the error:
App Inventor is unable to compile this project.
The compiler error output was
________Preparing application icon
________Creating animation xml
________Creating style xml
________Creating provider_path xml
________Creating network_security_config xml
________Generating adaptive icon file
________Generating round adaptive icon file
________Generating adaptive icon background file
________Generating manifest file
________Attaching native libraries
________Attaching Android Archive (AAR) libraries
________Attaching component assets
________Invoking AAPT YAIL compiler - AAPT execution failed. .

This is my first time doing an app, so I'm sure i have a lot of errors in the code.
In the configuration I want to change the size text, color of the text and the background color of the app.

Any extensions used? is there any really large asset?

any errors or warnings?

is tamañoDeLetra a list of labels or buttons?
later you try to set a button fontsize and label fontsize using the same component

you should initialize the list of your components using component blocks and have a list for labels and another list for buttons ...
