App Inventor is unable to compile this project, "the compiler error output was"

And what is the remix_history file for?

First time seeing it

it's working, I remove this file.

But I don't know where this file comes from, whenever I export the project it appears, strange :confused:

Just found it...

Please help me out I'm confused with this error, despite my deletion of many components block
I received this report: “App Inventor is unable to compile this project.
