this error appears everytime app reaches 50% compiltion
your error message is DX execution failed
this is a very general error message and therefore it’s hard to say, what might be the issue in your case
however there is SteveJG’s monster list of tips and tricks you can check for possible reasons…
let us know, what you find out…
i have checked almost every point mentioned in this list. Still does not work
unfortunately then I do not have any more ideas…
you might want to tell us a little bit more about your project… how many screens, assets, which components and extensions you are using etc.
