My problem is i have been able to use rstudio to write code for a long time. However, recently, when i start my rstudio, no matter which button i click or whatever I do, this "Error: Unable to establish connection with R session" pop up. When I tried to edit files, it shows up. When I tried to run code, it shows up. I couldn't remove plots. I could not do anything with Rstudio now. This is being a problem.
I uninstalled rstudio and then reinstall. The same problem still persists.
Please help. It's been a few days that this has been happening already. I really need a fix on this.
Below are the methods I have tried and the "Unable to establish connection with R sessino" still would not go away.
Resetting the Rstudio desktop by removing the entire folder.
Remove start-up files
Changing software rendering to "Software"
Uninstall R and RStudio and reinstall again.
I have attached my

None of the above works for me.
Can RStudio please look into it please ? I am working on my master thesis and the deadline is coming up.
Just notice that every time I started my RStudio, It reopened the multiple browser() windows (for debugging) that was closed previously.
