Studio version 648 is flagged by Windows Defender as a virus / PUP on installation. I utilize Roblox Studio Mod Manager as a bootstrapper, and it crashes upon attempting to perform a clean install of Studio, with Windows throwing System.IO.IOException: Operation did not complete successfully because the file contains a virus or potentially unwanted software.
It is entirely possible for Mod Manager to be at fault for this, but I cannot find a download link to specifically 648’s binary from ROBLOX. I did try reverting and force reinstalling version 647, and was able to with no problems.
Expected behavior
Studio to install and open as normal.
