unable to open discover_16: Mixed designs

[guavarouge]

What attempting to open the tutorial, I get the following error:

Error in shiny_prerendered_app(target_file, render_args = render_args) : No server contexts or server.R available for /Library/Frameworks/R.framework/Versions/4.3-x86_64/Resources/library/discovr/tutorials/discovr_16/discovr_16.Rmd Calls: .rs.sourceWithProgress ... <Anonymous> -> force -> <Anonymous> -> shiny_prerendered_app Execution halted

It had the same problem. It started working after i updated all of my packages (in this case shiny was the culprit). You might also experience problems with the "matrix" package, at least i did.
