I have the same versions of the packages installed on two computers with Ubuntu 22. However, when running the example of the filter_select function from the documentation, in one case it looks good and in another it doesn't and the error remains when knitting and generating the .html
sd <- SharedData$new(chickwts)
filter_select("feedtype", "Feed type", sd, "feed")
packageVersion("crosstalk") = ‘1.2.0’
packageVersion("flexdashboard") = ‘0.6.2’
