    I have made a Unity Project with 2 scenes:
    1. The main menu screen:


    2. The Ar session Scene


    I have Also enabled ARCore in Player -> XR Pluggin Management. -> ARCore
    When I hit play the App crashes. I have tried the following:

    1. Changed the ARFoundation and ARCore Version from Package Manager.
    2. Tried a basic and plain new Unity Project in both Unity 2020 and 2019.4.
    3. Restarting My Phone Numerous times.
    4. Trying APK on other Android devices of my Family and Friends (It works on their device just fine)

    One thing I have noticed is that any project without AR-Session in the hierarchy runs just fine (Which explains why the App doest Crash in the Main Menu Screen)

    But as soon as it tries to load an ARSession, it crashes.

    I managed to get the crash report which is attached below:

    Code (CSharp):

    Based on the troubleshooting done, I dont see the following as responsible for the crash:
    1. Unity (Any version).
    2. ARCore / ARFoundation.
    3. Project itself.

    Can someone suggest any device settings for android to fix this? Because I have also found that usual solution is to Factory reset the device. Which I am avoiding, as its my personal phone and not a test phone.

    Also if anyone have additional troubleshooting that I can do please let me know.

    Thanks in Advance!

    Phone: POCO f1, Andoird 10
    Unity: 2019.4, 2020
    ARFoundation: 4.1.0 (or any other version results in the same outcome)
    ARCore: 4.1.0 (or any other version results in the same outcome)

    Okay, thank you I'll try it tomorrow and let you know if it works!! Thanks for your help

    EDIT: It worked. Thank you! For anyone else having this problem here are the detailed steps of what to do:

    1.Go to Build Settings -> Player Settings -> Other Settings:
    Under Configurations Change the Scripting Backend to IL2CPP
    2. Under the same, tick ARM64.

    3. Rebuild and Deploy the project, it should work now!

    Had the same issue!!! You guys are a life saver!!!!
    Worked perfectly for me too.
    The weird thing is that I worked fine on my phone (Samsung Galaxy S9+) the night before.
    After waking up the next day to work on it, it suddenly stopped working...
    I was so close to a rage quit.:confused:

    ARCore doesn't work 32bit anymore. Use IL2CPP with 64bit.
