I am currently working with R version 3.6.1, RStudio 1.2.1335 in Windows 10 and the latest version of shiny package.
I uninstalled R, RStudio, removed the shiny package and reinstalled everything, but it didn't work.
Thanks

Do you have any additional information you could provide us? Also it seems like you have non ASCII characters and empty spaces in your windows user name, this usually brings some unexpected issues when working with RStudio products, could you try changing your user name?
