Steps to reproduce:

Have you been able to reproduce this issue with just the Firebase Unity quickstarts (this GitHub project)? What’s the issue repro rate? (eg 100%, 1/5 etc) 100%

What happened? How can we make the problem occur? This could be a description, log/console output, etc.

If you have a downloadable sample project that reproduces the bug you’re reporting, you will likely receive a faster response on your issue.

Relevant Code:

// TODO(you): code here to reproduce the problem

https://github.com/firebase/quickstart-unity/issues/1130 It seems that the compatibility of the Unity-SDK package cannot be maintained. In a Windows environment, it works fine.

I resolved this Issue on Mac by simply Going to the Folder

1. Assets>Firebase>Plugins>x86_64
2. Right-click on the FirebaseCppApp-11_2_0.bundle and select open with vs-code
3. Select Open anyway on the prompt message. Once the file is opened in vs-code you can simply run the unity editor and it will work.

My environment is not MAC, so I don’t get a warning. It is possible to open the file in VS Code. We are aware of the issues that occur with MACs. I believe that the problems that occur on Linux are occurring separately.
