[Bug] Unity App Crash on launch with Firebase 12.10.0

[mmiro1]

Description

After upgrading the Firebase SDK from 12.1.0 to 12.10.0, on some Windows PCs the app crashes on launch.

I have tried to use the FirebaseApp.CheckAndFixDependenciesAsync().ContinueWithOnMainThread instead of FirebaseApp.CheckAndFixDependenciesAsync().ContinueWith, and also, I have tried to wait some frames before calling that method.

For now I have downgraded to 12.9.0 and the issue seems to be resolved.

I have seen this issue too and the last message seems to be the same problem, I wanted to open another one since that one is pretty old.
#728

Thank you in advance.

Reproducing the issue

I have two similar computer with the same Windows version, in one the app crashes with the SDK 12.10.0 and the other works fine. The build with the SDK 12.1.0 & 12.9.0 works on both computers.

I have attached the Player.log, the crash.dmp and the PC specs:

I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.

Hey @mmiro1, thanks for reaching out. While we investigate this further, could you help answer a few questions below:

1. Is the issue consistently reproducible?
2. Just to confirm, you mentioned that the problematic SDK is App Check. Is the issue only specific to App Check SDK, so the issue is not reproducible when App Check is excluded?
3. Are you able to able to reproduce the behavior on an MCVE?
4. Could you check if the latest Visual C++ Redistributable for Visual Studio 2015-2022 is installed on both windows machine? Or perhaps are using the same version?

In my investigation, it doesn't seem like we had any changes from version 12.9.0 to 12.10.0 that's related to this issue, aside from using latest windows version in workflows.

Hi @argzdev , thank you for the fast reply.

1. Yes, the crash happens 100% of the times on the affected PC, and I have reports of users with the same issue and stacktrace.
2. Sorry I may have missclicked. I wanted to mark the App Core SDK. I am not sure which of the installed SDKs is the responsible for the issue, the only information I have is the stacktrace from the Firebase App Core.
3. I haven't tried this yet, as mentioned I have downgraded the SDKs version to 12.9.0 (were I don't have issues) and I am currently trying to deploy a build for affected users.
4. On the affected PC the versions are: Microsoft Visual C++ 2015-2022 Redistributable (x64) - 14.29.30133 & Microsoft Visual C++ 2015-2022 Redistributable (x86) - 14.30.30704. And in the PC without issues: Microsoft Visual C++ 2015-2022 Redistributable (x64) - 14.42.34438 & Microsoft Visual C++ 2015-2022 Redistributable (x86) - 14.42.34438.

I did look the patch notes to but nothing related to Desktop did appear.
