一、紧急恢复操作
查找具体PID后强制终止：
rstudio-server active-sessions
rstudio-server kill-session [PID]
清理会话缓存文件,同时清理临时目录：
rm -rf ~/.local/share/rstudio/sessions/* ~/.rstudio-desktop .rproj.user
rm -rf ~/.config/rstudio/* ~/.cache/rstudio
find /tmp -maxdepth 1 -user "$USER" -name 'rsession-*' -exec rm -rf {} +
重启RStudio服务
sudo systemctl restart rstudio-server
