[GabrielJadderson]

[REQUIRED] Please fill in the following fields:

• Unity editor version: 2020.3.45f
• Firebase Unity SDK version: 11.2
• Source you installed the SDK: upm
• Problematic Firebase Component: Platform
• Other Firebase Components in use: Platform
• Additional SDKs you are using:
• Platform you are using the Unity editor on: Windows
• Platform you are targeting: Android & iOS
• Scripting Runtime: IL2CPP
• Pre-built SDK from the website or open-source from this repo: Pre-built SDK

[REQUIRED] Please describe the issue here:

Unity crashes randomly while compiling scripts. Happens very very often atleast once an hour.

Steps to reproduce:

Have you been able to reproduce this issue with just the Firebase Unity quickstarts (this GitHub project)?
100%

What happened? How can we make the problem occur?
just write some code and wait for unity to compile then it will crash randomly.

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:

Stacktrace of the error, It's always the same stacktrace.

These are the dependencies I am using:

The error happens in this dll "FirebaseCppApp-11_2_0" the entrypoint is in this function "Firebase_App_CSharp_PollCallbacks"

This is a crash minidump:

This is how frequent the crashes are (the gap is when I went on vacation):

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

Hi @GabrielJadderson,

Thanks for reproting this. I noticed that you're using version 11.2.0 of the Firebase Unity SDK. This makes use of version 1.2.176 of the External Dependency Manager. Could you try that version of the External Dependency Manager and see if the issue persists?

[GabrielJadderson]

Hi, I updated the External Dependency Manager on Friday to 1.2.176 from 1.2.175 and got a crash today again.

@GabrielJadderson This happens to me all the time as well. They haven't fixed it for at least a year. It's absurd considering how much they get paid. I recommend turning off all firebase related game objects when in the editor. That worked for me (while not working on firebase related development). Wish they would fix the problem or at a minimum improve the debugging logs. I don't think they have any clue what the problem is and I'm not entirely convinced they care. Hopefully Supabase comes with official Unity support one day. At this rate Google is gonna kill this product any day now.

Related issues with no resolution or concern to actually fix:
#570
#819
#777 closed by bot even though it's broken. Devs didn't reopen it
#768 closed by bot even though it's broken. Devs didn't reopen it

Most people don't report these issues they just stop using low quality software...

Hi folks,

We are very interested in addressing and fixing issues with the Unity editor crashing, but we currently have a hard time investigating them. It would be immensely helpful if you can provide something which we can locally replicate (e.g. a minimal, reproducible example) as a basis for troubleshooting.

@GabrielJadderson I see that this issue makes use of Authentication. Are you caching your User object? If so, one of our engineers shared a workaround where the Auth object is being cached, and the User is accessed by the CurrentUser property.
