Again, if R was using 25% while showing the prompt and waiting for

25% CPU is used by R. And R shows the prompt and waits for user input.
Here is a report of the CPU usage by Rgui from Windows command line:
C:\Users\Jinso>typeperf "\Process(Rgui)\% Processor Time" -si 5
....
"04/28/2020 13:31:05.895","-1"
"04/28/2020 13:31:10.915","0.622494"
I'm not sure how to interpret this.
And I don't see where you get the 25% from.
The number in second column divided 4 would give the CPU usage, so, if
the number is 100 or above, then the CPU usage is 25% or more...
I was suggesting something resembling the top command.
(Re-iterating, I misinterpreted the ps command).
There are no ``top'' command on Windows. And I am not familiar with the
command line utilities on Windows.
Since I can not reproduce the same problem using R 3.6.3, I think it is
a bug in R 4.0.0. I have filed a bug report.
Thanks a lot for your help.
Best,
Jinsong
