I have encountered a debilitating error on my Windows 10 machine.
Basically, I removed and reinstalled R while Rstudio was running and afterwards, each time I try to open an Rstudio file I get the
Fatal error: Unable to open the base package and Rstudio opens as a blank page.
To remedy the situation, I have completely removed and reinstalled both R (version 4.0.0) and Rstudio (version 1.2.5042) but the fatal error message still persists, I highly appreciate any solutions?
