This error is larger and have more "Duplicated resources".

I see that is a problem with the images i use inside the aplication But that is only one image with those names with the name inside the app, why is "duplicated"?

and other assets like "node_modules_reactnavigation_stack_src_views_assets_backicon" assets on react navigation that i dont have control.

Delete drawable folder and raw folder.

Your project directory will be like that:
