Ionic V1 apps - problems in starting after going to background (sporadic issue)

EDITED : I had assumed it was related to FileUtils (cordovan-file) but its not.

The problem in a more generic sense is the app freezes in its splash screen after going to the background - only sometimes. Any experience?

Freeze logs (happens after I exit the app via home/back and only once in a while)

===== OLD POST =======

Hi folks, has anyone faced an issue with a v1 app when after going to the background (back or home), it randomly refuses to restart with “FileUtils: Unrecognized extra filesystem identifier: assets” error? It happens once in a while. This is the last error before the app freezes at the splash screen

It is almost like the device is not ready on resume --> but I’ve wrapped all parts of my code (I can think of) in $ionicPlatform.ready()

Only Android.
