I recently encountered issue with Rstudio. It opens as blank screens with menu bar but if I click on anything, nothing happens.
I also tried some troubleshooting from the community forum - https://support.rstudio.com/hc/en-us/articles/200534577-Resetting-RStudio-Desktop-s-State. This didn't help. Therefore, I tried other troubleshooting as well- https://support.rstudio.com/hc/en-us/articles/360017886674-Troubleshooting-RStudio-Rendering-Errors.
This time I got the error the location is not available.
