Perhaps the fact that Steam is installed onto my SSD is causing the conflict. Steam.exe & Arma3.exe are both not administrator-only executables. Additionally, I receive the "0x50001002: Failed to mount the work drive" error when I attempt to run the mapdisk.bat file. I also haven't updated my version of Windows after the update that was released on the October of last year because I was unable after my first and only attempt to install it. My computer frequently crashes programs and freezes as well. Perhaps that may have something to do with the error specifically?
