I have been using RStudio for a few years, but for some reason it has stopped working sometime in the last few weeks and I cannot get it to run at all now.
The version I had was 1.4.1717 desktop with R version 4.1
I have tried uninstalling and reinstalling, both with the 1.4.1717 version, and also with the latest version 2021.09.0-350 with the latest R version 4.1.1 x64
I am running Windows 10 with latest updates installed
I have tried to run RStudio diagnostics but there is no output
I have tried holding down the control key when clicking on the program but it makes no difference
I have tried deleting or renaming previous RStudio folders
I have tried resetting my PC to a previous state of a few weeks ago - it still doesn't work
I have tried downloading and installing both R and RStudio onto a different Windows 10 machine - it works fine on the other machine (although I haven't tried to copy across all my packages)
I have tried rebooting my PC with most services and startup tasks disabled - it still doesn't work
I have tried briefly turning off my Windows firewall - it still doesn't work
I cannot find any other information online that is giving me any clues. Please help!
