Unity Android app critical crash when it's set as default home (when home button is pressed)

Question

I'm developing an Android application with Unity and one of the requirements is that my app asks for a set default home in the device.

I was looking everywhere and I read many tutorials in order to do that.

But when the screen of defaults home apps are showed and after that the home button is pressed, my app crash!!

showing the next output in the logcat

[UPDATE] Full output

I tried many things.

Change the unity version. Select different levels Target API for compile

Currently, I'm working with Unity 2018.4.4f1

This is set in my manifest file...

<category android:name="android.intent.category.HOME" />
<category android:name="android.intent.category.DEFAULT" />

Finally, I could find a temporal solution doing this.. the error keeps showing sometimes and I don't know what is the reason.

Sometimes when another app is open and the home button is pressed this error occurs again

Does anyone happen the same?

You're dereferencing a null pointer somewhere in C code, in the libunity library. Beyond that, you've cut off any more useful parts of the stack trace. — Gabe Sechan, Aug 20 '19 at 15:16
Hello Gabe Sechan.. ok but I do not touch that file, if you can create an empty project in unity and just add this lines in your manifest file ** ** run in your device and after that press home button the error occurs. — eflores, Aug 20 '19 at 15:27
That's the unity library. If you're making Ann app that uses unity, you're using it. Most likely you're passing it bad data somewhere. — Gabe Sechan, Aug 20 '19 at 15:29
yes the app that I making is made in Unity.. but as I said before, when you create an empty project with Unity and add those lines, this error occurs, maybe unity try to access to some location inside the libunity library, I don't really know how to track the error — eflores, Aug 20 '19 at 15:41

Unity Android app critical crash when it's set as default home (when home button is pressed)
