[Rd] R 4.0.2 64-bit Windows hangs

[Duncan Murdoch]

Are you normally running from Visual Studio, or only when trying to 
debug?  Where did you download R from, and which version?  The bug 
report mentions Registry key

HKCU\Software\Microsoft\InteliPoint\AppSpecific\Rgui.exe

which I believe is installed by the Microsoft R Client rather than the 
CRAN distribution of R.
