When trying to launch R from terminal (powershell or git bash on win10), one of my students is simply returned to their prompt instead of being launched into the interactive R prompt. Interestingly, when they try to launch cmd from powershell, they run into the same error, does R depend on cmd working and there is a deeper problem to why this fails, or do you think it is R specific? When they try to install from github with devtools, they get the error system command 'Rcmd.exe' failed, exit status: 1, stdout + stderr empty.
A similar question was asked here without response. We tried disabling file sync and security services but to no avail.
