All these shortcuts do is launch cmd.exe or bash, optionally after
setting %PATH%, optionally in a non-standard terminal application.
Evidently, something in the %PATH% set by the shortcuts conflicts with
the R CMD check process.

For a package that doesn't have any compiled code, there should be no
need for these tricks. Just start cmd.exe (for example, using Win+R,
"cmd", Enter), navigate to your package and run something like
"C:\Program Files\R-version\bin\R.exe" CMD check sos_2.1-4.tar.gz.

If you're still having problems, try editing your %PATH% and trimming
anything you don't need from there.

If you're sure you need a special shortcut to launch a command line to
check your package in, try installing Rtools and performing checks from
"Rtools bash".
