Native Crash On my PlayStore app I can's seem to solve or reproduce

Hello to everyone and happy holidays.

I have an app that uses a specific image background resource for all activities. So I've set on the values\styles.xml file the following on my style:
<item name="android:windowBackground">@drawable/toolbar_background</item>

I have resized this image to match drawable-ldpi / mdpi / hdpi and xhdpi standards, on my resources. This was working fine on my first few production releases, until I started getting some weird native crashes on the PlayStore crash reports. The most relative thing I found after a lot of research was a post from this forum addressing the problem and blaming the background image, and that made a lot of sense to me(most users experiencing the crash reported the crash happening when a new activity tried to start). Link here. But what it suggested was already ok on my part.

I checked out my repository history and I hadn't made any changes affecting this. But the crashes kept coming. On an other app update I tried to update Xamarin, Java JDK, Android sdk and I tested it on a device that reproduced the crash and it seemed to be resolved. A few days after the release of the update, the crash kept being reported (maybe less frequently).

Could anyone have any clue or any suggestion on how I should try to debug this? I've tried anything I could possibly imagine but I still come short.

I have noticed that this crash is only reported on devices using armeabi-v7a native platform.

Here are some sample crash reports and some specs for my app:

xhdpi image resource sample:

I also use Xamarin.Android.Support.V4 version v23.4.0 and Xamarin.Android.Support.v7.AppCompat v22.2.1

Any help would be much appreciated.

Thank you guys.
