you probably have an invalid color defined for your splash screen

What colors are invalid? does the splash screen support .png?

Here is my splash screen from app.json


  "splash": {
      "image": "./assets/launchscreen.png",
      "resizeMode": "contain",
      "backgroundColor": "#ffffff"
    },

looks correct to me. what other colors are you using in app.json? android status bar? navigation bar? they should be hex colors in the exact format that you provided above

5 
   "orientation": "portrait",
    "icon": "./assets/icon.png",
    "splash": {
      "image": "./assets/launchscreen2.png",
      "resizeMode": "contain",
      "backgroundColor": "#ffffff"
    },

...
 "notification": {
      "icon": "./assets/logo96x96.png",
      "color": "#00000",
      "androidMode": "default",
      "androidCollapsedTitle": "MyRewards",
      "iosDisplayInForeground": true
    },

...

 "androidStatusBarColor": "#00c497",
    "androidStatusBar": {
      "barStyle": "light-content",
      "backgroundColor": "#01cca1"
    },

I also swapped the launchscreen.png for one with a plain color. Could it be the format?

cjs-MBP13-2017:assets cj$ file launchscreen.png 
launchscreen.png: PNG image data, 1242 x 2208, 8-bit/color RGBA, non-interlaced

there are 5 zeros there, should be 6.
