@troZee I found one reliable way to replicate this bug.

Have the pager render behind the Android permission request popup.

For me, when I start my app, it requests for an Android permission immediately. Behind the popup, I see my app rendering and it crashes as soon as it tries to render the pager stuff. If I dismiss it (i.e. Allow or deny the permission) quick enough, it will not crash

Good news! It has been about one week after I pushed an app update. So far we longer see the crash!

@cojj90

For now, as a workaround, we added an explicit check in JS to check for Android activity before rendering pager-view

Could you provide a code snippet of that solution ? I would like to take a look on it.
