fastqCleaner failing to launch in RStudio

Question

When I execute:

> FastqCleaner:::launch_fqc()()

I get the following output

Have I done something wrong or is the function broken in some way?

The issue is with the navbar page, downgrading shiny to 1.6 or in my case 1.4 fixed it for me, the detailed link to find to the solution is here: https://github.com/rstudio/shiny/issues/3556
