hi @shenjun - it would be really helpful for you to include the version of RStudio, operating system, etc that are in the body of your post but are not filled out! A more complete description of the problematic behavior would be helpful as well. Does RStudio ever open properly? Have you tried reinstalling?
I have filled in the post about the version. In the diagnostics report ,there shows something error and break off. It open properly before the problem came, and I tried reinstalling two times but the results were same. Now I download the older version of Rstudio :RStudio Desktop 1.0.153 for Windows, and it just work out , but I can't also use the newest Rstudio.
thank you!
after I double click the Rstudio , there are nothing show in the screen but a icon on the bottom taskbar, and I click the taskbar ,nothing but a blank small retangular(1cm*4cm)
