After some packages update, I'm no longer able to start my shiny application. The error I'm receiving it's not very clear:
Warning: Error in : Internal error: Unknown
Error : Internal error: Unknown
I'm quite sure that this error is related to some update as, the same application works fine within another machine with the same R version (4.0) and the same Shiny version (booth are MACos).
Do some of you know how to trouble-shooting this?
