Steps to reproduce:

We are in the process of updating out app to unity 2022.3.35f1 We updated our firebase version from 9.1.0 to 12.1.0. while the build succeeds, on arriving to the home screen we get the above errors. We have done some research into others who have faced this problem however none of their fixes have worked for us

Attempted Resolutions:

• higher min sdk version (23 > 24)
• Force resolving using EDM
• Tried removing firebase/EDM and reinstalling
• Tried removing firebase and install using the .tgz/package manager method
• Tried updating EDM to the newest version
• Tried relocating the FirebaseCppApp-12_1_0 files
• Tried enabling 'any platform' for all FirebaseCppApp-12_1_0 files
• Update Microsoft Visual C++ 2015-2022 Redistributable to the latest version
• Updating Gradle to 8.0+
• Updating NDK (not sure this valid)
• Fresh unity install
• Rolling back Firebase to Unity 12.0

Hi @ClairePeta-36, thank you for reaching out. The Firebase Android SDK repository handles issues related to native Android . To get better help, I suggest filing the issue in the Firebase Unity SDK. Thanks!
