Error Information:
Description of issue -
I was working in RStudio, but it crashed and closed. When I reopened it, it was empty. I uninstalled and reinstalled RStudio, but when I open it, a window appears with an empty menu. Additionally, in Task Manager, RStudio shows four processes running and is using 80% of my RAM.
Attempted steps taken to fix -
I uninstalled RStudio and R several times. I reinstalled them, but the same error persists. I cleaned up the AppData files as I saw in some tutorials, but nothing worked.
