R- debug: line by line through a loop

I try to find a way to debug through R studio, however all the solutions I can find do not really work.

1.) CTRL+enter: works but does not go through every iteration of the loop but only once.
2.) Adding "browser()" stops at that point but I am not able to go from there line by line (neither "n" nor "F10" works?

Any idea what the issue could be?

Put the code/script inside a function:

function_to_debug <- function(data){ 
     a = 2+3 
     return(a)
}

Then run this in R console:

debug(function_to_debug)

The debugger starts and you can step through each line of the function.
