For example, in a new R session:

library(thematic)
thematic_on()
plot(1:5)
sessioninfo::session_info()

I believe the problem is from here:

thematic/R/auto.R

Lines 204 to 206 in 19113ad

	shiny_output_info <- function() {
	if (!is_installed("shiny")) return(NULL)
	info <- tryNULL(shiny::getCurrentOutputInfo())
