my shinyApp does not load correctly. Any application however simple it is it displays this gray screen with names but nothing works. I already installed the package again and R. I updated everything that was possible and still nothing ...

SInce you did not paste any code, try this:

library(shiny)
library(DT)

shinyApp(
  ui = fluidPage(
    DT::dataTableOutput("mtcarsTable")
  ),
  server = function(input, output) {
    
    output$mtcarsTable <- DT::renderDataTable({
      
      DT::datatable(datasets::mtcars[,1:3], 
                    options = list(rowCallback = JS(
                      "function(nRow) {",
                      "var full_text = 'Test1';",
                      "var full_text1 = 'Test2';",
                      "$('td:eq(0)', nRow).attr('title', full_text);",
                      "$('td:eq(1)', nRow).attr('title', full_text1);",
                      "}")
                    )
      )
      
    })
  }
)

Try that and see if shiny loads correctly

the error continues with your code. The error only occurs with versions of R> 3.5. I made a shiny 1300 lines of code recently in 3.4 and there was no problem, but I need to use packages that are asking for newer versions.

The error only occurs with versions of R> 3.5.

That is not correct. I am running

sessionInfo()
R version 3.6.0 (2019-04-26)
Platform: x86_64-pc-linux-gnu (64-bit)
Running under: Manjaro Linux

I ran the code I gave you and get datable output. I just updated R two days ago and reinstalled all my packages. I keep a backup of all my installed packages and they get reinstalled back. If you can not run the shiny app above then you have more issues with your installation
