Likely.

But it may not be an ESS problem per se. 

M-x R starts a process that runs asynchronously. In interactive use there 
is no issue (barring something in .First() that slows the startup for
a very long time).

But, ...

If the  (rename-buffer ...) in org-babel-R-initiate-session
runs before all the setup that ESS performs in the process buffer is 
complete, chaos can result.

Not sure what the best way is to fix this.

A simple hack to temporarily solve the OP's problem is to force a pause 
before (rename-buffer ...) with (sleep-for 0.1) or something.

HTH,
