Screen Not rendering

Hi, I am using this realistic glitch effect. It works great in the editor, but when I build it the screen flashes on (with all effects applied), then goes black. Here's some more info: I have 4 cameras in the scene. All have the CRT effect. One of them only has the CRT effect, which is the one the scene starts and ends with, two have to CRT effect and the scanner effect, and one has the CRT effect and the Unsync effect. The camera with just the CRT effect and the one with the unsync do not render. The cameras with the Scanner effect do show up, but without the CRT effect. My screen space overlay canvas does show up. My graphics is OpenGL Core. You can find my always included shaders in the following picture. I looked at the scripts to see which effect used which shader to only apply shaders I needed. Loading all shaders yields the same results.

Any ideas?
