Can you run multiple instances of UE5 on windows at once?

Is it possible to run multiple windows UE5 apps? The UE5 windowed app would not be a full blown game, it would just be a special kind of video player. I need to have multiple windows to play different video streams. Would doing this be a huge drain on system sources? (I figure the dlls are shared, so that multiple instances would not really be a huge drain. The “drain” would come from whatever resources each instance would create and use)
