Unable to deploy my Shiny App with shinyapps.io

Thanks in advance for your support about the following issue. I want to deploy my shiny app on shinyapps.io.
It runs perfectly using R-Studio, but it returns a lot of erros that I can't fix at all when I'm trying to use that server.

They are located at the root with no subdirectory folders whatsoever.

Can somebody help me with this issue? I don't know what else should I present to you in order to understand what the issue could be. The following are the errors that shinyapps.io returns:

An error has occurred
The application failed to start (exited with code 1).

Are you using non ASCII characters in your app? I have experienced some issues with accentuated characters (from Spanish) and deployment to shinyapps.io, just to confirm if this is the case try removing any non ASCII characters and deploying again.
