Unable to entablish connection with R session

I checked as you told me to, I'm currently running the base R (3.6.3) and RStudio (1.2.5033). I even tried unnistalling it and installing it again, but the same problem keeps appearing.

About reseting RStudio's state, I can't type the command to access the RStudio-Desktop Directory and the menu bars are not clickable

I saw some people had the same issue but in the end there doesn't seem to be a solution

Do you have an idea of what might be happening?

Thanks in advance
