Opening Another Application in R Then Hangs

Sparks, John 
Hi R Helpers,

I am trying to open another application from within R and then work with it.

I can get the application to open, but R then hangs at that point (spinning blue circle in the middle of the screen) and my subsequent programming does not execute.

Does anybody know how to get R to unlock?

I am using Windows 10 and R4.0.

The example below freezes R on my machine.

Any guidance appreciated.  Thanks.
