Scene capture not working in packaged game

I set up a pair of monitors in my game showing a live feed from security cameras placed in the level, and they work fine in the editor. But in my packaged game the image on the top right monitor is not showing at all, basically just black. The left one looks fine though.

Since both screens and their materials are sharing the same parent material (screenshot below), the only difference is the texture sample (to capture different locations on the map), so I can’t figure out what the problem is and why only one of them is not working and why the problem only exists in the packaged game and not in the editor. Please help me out!
