The Rstudio has been working well, but it recently stops working and the problem cannot be fixed after re-installing all the packages. I deleted all R, Rstudio and R packages, and successfully re-installed all the packages, but the Rstudio still stops working if I quit and restart the R session. No any files can be shown on right side and no response when pressing "Enter" button .
Then, I have tried to run the Diagnostic report, here is a part of message from the report.
