I've been using Rstudio without problems for long time. Suddenly, today I can see only the main window without unresponsive menus. I've tried to reinstall Rstudio and R, reset Rstudio Desktop and use software rendering, but without success. Main info: Win 7 Pro, Rstudio ver. 1.4.1106, R ver. 4.0.4 (64 bit). Classical R console works well. I've also prepared diagnostic report but I can't see how to attach it as the file to this topic.
EDIT: After a few hours, it works... I still don't know the source of this problem.
