[Bug] Crash on Android after adding AppCheck with Play Integrity

[OleksiiSB]

[REQUIRED] Please fill in the following fields:

• Unity editor version: 2021.3.31f1
• Firebase Unity SDK version: 11.2.0
• Source you installed the SDK: unitypackage
• Problematic Firebase Component: AppCheck
• Other Firebase Components in use: Auth, Firestore, Installations, Analytics, Crashlytics, Remote Config, Functions, Storage
• Additional SDKs you are using: Facebook, Applovin, AppsFlyer
• Platform you are using the Unity editor on: Mac
• Platform you are targeting: Android
• Scripting Runtime: IL2CPP
• Pre-built SDK from the website or open-source from this repo: Pre-built SDK

[REQUIRED] Please describe the issue here:

After adding initialisation of the AppCheck we see random crashes from random set of devices that have AppCheck mentioned in the crash reports. We also have App Attest on iOS and it does not have similar problem. Sadly I was not able to repro this on the set of test devices we have and have only crash reports available to look into.

Reported from all versions of Android and all manufacturers. Distribution is similar to what we have in general distribution for all installs, so I don't believe this is somehow dependent on Android version or manufacturer.

Hi @OleksiiSB,

In order to ensure that your app has the latest updates and bug fixes, could you try if the latest SDK version (11.5.0 as of writing) makes a difference?

[OleksiiSB]

We have updated SDK to the latest version for the new update that will start rollout Wednesday or Thursday. I will monitor crashes and update here as soon as we have info.

[OleksiiSB]

We didn't get to the public rollout to confirm that issue is still present after updating to latest 11.5.0 SDK. Report came from the closed beta user, so I can confirm updating does not resolve the issue. I also didn't find any mentions of changes related to the AppCheck in release notes of Unity SDK or Android SDK updates that were included between 11.2.0 and 11.5.0 Unity SDK versions.
