Player Settings window is no longer displaying any information

UI Elements



Priority: 2Necessary for shipping a final release


Severity: 1Crash, freeze, data loss, work stops

Repro Steps:
- have Unity Editor with the Android build tools installed.
- download this project and load it on Mac - I'm on macOS Mojave 10.14:
- Got to project Settings-> Player
- notice all the errors and that the player settings don't show anything

Does not occur on Windows.
I've tried:
- reopening the Project Settings Window
- restarting Unity
- restarting my Mackbook
- reinstalling Unity
Nothing seemed to allow me to use the Player settings window again
If i make a new project, the player settings window will default back to Mac Standalone settings and that seems to fix it, but then it breaks back again as soon as I turn to Android Settings again. This, in turn, makes setting up a build for Android impossible, so it's a major blocker.
