Screen.resolutions doesn't return full list in build

In Unity 2018.3.7, I noticed that Screen.resolutions stopped returning the full list of resolutions both in the editor and in the Windows build. The only result that I get is "2560 x 1440 @ 144Hz", which is the resolution of my primary monitor. Here's the relevant part of the code (the selectableResolutions part is to remove duplicates):

Code (CSharp):

1. Resolution[] resolutionsTemp = Screen.resolutions;
2. Vector2 prevRes = Vector2.zero;
3. string screenResolutions = "";
4. string selectableResolutions = "";      
5. for (int i = 0; i < resolutionsTemp.Length; i++)
6. {
7.      Vector2 resVec = new Vector2(resolutionsTemp[i].width, resolutionsTemp[i].height);
8.      if (prevRes != resVec)
9.      {
10.          selectableResolutions += resolutionsTemp[i] + ", ";
11.      }
12.      prevRes = resVec;
13.      screenResolutions += resolutionsTemp[i] + ", ";
14. }
15. print("All resolutions supported by monitor (retrieved via Screen.resolutions): \n" + screenResolutions);
16. print("All resolutions selectable in the game: \n" + selectableResolutions);
17. print("Total available resolutions: " + Screen.resolutions.Length);

And in the build, this gives me:

Code (CSharp):

1. All resolutions supported by monitor (retrieved via Screen.resolutions):
2. 2560 x 1440 @ 144Hz
3. (Filename: C:\buildslave\unity\build\Runtime/Export/Debug.bindings.h Line: 45)
4. All resolutions selectable in the game:
5. 2560 x 1440 @ 144Hz
6. (Filename: C:\buildslave\unity\build\Runtime/Export/Debug.bindings.h Line: 45)
7. Total available resolutions: 1
8. (Filename: C:\buildslave\unity\build\Runtime/Export/Debug.bindings.h Line: 45)

This code definitely worked before, so I'm not sure if it's a Unity bug or if I messed up somewhere. Can anyone confirm if this is working correctly in 2018.3.7?
