RStudio isn't working; it's empty

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.

System Information:

  • RStudio Edition: Desktop
  • RStudio Version: 2026.01.1+403
  • OS Version: Windows 11 Home Single Language
  • R Version: R-4.5.3-win
  • Output your diagnostics report (if possible):

Otherwise it could be the location of where R is installed?

Also you could try installing a previous version of RStudio, if you have not done so already.
