r - When I set the working directory in R, it doesn't recognize at first

Question

When I am using R and I change my working directory, the first time that I want to import a file from the new working directory, the window that pops up from which I have to choose my file is still on the previous working directory. I have to close it and the second time that I want to import it, it is on the right working directory.

I don't know where this problem is coming from. I updated my R and RStudio to the newest version but still have the same problem. Could anyone help, please?
