Hello! Thank you for the report.
I am pretty sure we have some flaw relater to re-joining IDE processes after Ctrl+R because Ctrl+R restarts only one of them. But may I ask why do you use Ctrl+R? What are you achieve when reload the IDE. It used to have much sense previously, but now I see no clear reason.
Am I understand correctly, you reload to switch to an empty/dummy project? If so, can’t the Ctrl+Shift+N or opening a particular project (Ctrl+O → Recent) do the trick?
