I build a shiny app like described here: https://mastering-shiny.org/scaling-packaging.html#sharing
I created a file called app.R in the root directory of my app/package which includes:
pkgload::load_all()
shiny::shinyApp(ui = appUI(), server = appServer)
When I run this file locally, everything works. devtools::check() also works and has neither errors, warnings or notes.
When I try to deploy the app to shinyapps.io, the app fails to start with exit status 1.
The log say:

Does anybody know, why I get this error? the class is installed and exported in the NAMESPACE.
