I am new to R and R Studio and have tried to install R (4.2.1) and R Studio (RStudio-2022.07.2+576.exe) Windows 10 PC. But see only the top line of tabs (File, Edit, Code, View etc) these tabs get highlighted when clicked but nothing happens i.e. no options are shown under any of these tabs.
Have you tried changing to software rendering?, you can change it by holding the Ctrl key while opening RStudio, then you should see this menu and change the "Rendering Engine" to "Software".
Close Rstudio and R. Open the folder C:\Users<username>\AppData. Go to the folder "Roaming" and delete all folders with names R and Rstudio. Then from AppData folder, go to the folder "Local" and do the same. Then start Rstudio.
