[Bug] Constant Editor Crashing on Using Firebase

[Moe-Baker]

Description

For the past 4 months our project has been plagued by constant Unity editor crashes.
After opening the project, the first play mode launch works fine, but the possibility of crashing starts racking up after that. It used to crash after every 5-6 play modes, now it crashes after about 2-3, and sometimes while just compiling code.

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

Hey @Moe-Baker, thanks for reaching out. For runtime crashes, I'm guessing that the instantiation of multiple SDKs using async/await could potentially introduce race conditions if ever any call to its functions is made before finishing initialization. As for compilation crashes, this is very rare, and could mean a bug within our SDK or an issue with the integration setup.

That said, are you able to reproduce the same behavior with an MCVE? If so, any chance you could share this with us? It'll help us investigate this issue further.

[Moe-Baker]

I can't really validate it with a minimal project; it's a very random crash.
I'll investigate the async SDK usage.

This crashes usually happening when we disable domain reloading while entering play mode and making C# script changes while in play mode. FirebaseStorage.OnAppDisposed() is the reason I believe (I think it is triggered from Firebase.FirebaseApp:Finalize() -> Firebase.FirebaseApp:Dispose (bool)). All crash logs points to this. I had many crash logs when I created a bug report to Unity, but after the report I deleted them all. And Unity said "this is a third party issue".

Edit: This is happening Windows 11, 10 and macOS (both Intel & Apple Silicon). Unity 21 LTS and Unity 6
