This happens only on one machine. on other computers, everything works fine, without any problems. We have also tried version 9.3.0, but got the same error. previously we had version 8.8.0 and had no exceptions.

Steps to reproduce:

Here minimal repro of this problem: TestCrashlytics it has nothing special but it reproduces the error on that machine Steps used to reproduce the issue:

1. Clone the repo;
2. Import project into Unity for the Android platform;
3. Import Firebase Crashlytics SDK into the project;
4. Add package id;
5. Add google-services.json into the project;
6. Open SampleScene;
7. Hit Play

HI @paulinon

We found the issue. On that single machine was installed C++ Redistributable 2005, 2010, 2012, 2013, 2017 but not newer. Installing C++ Redistributable 2015-2022 fixed the issue.

So I’m closing this issue. Thanks for your help!
