One of the must-select scenes:

1. Enter the login page of xxx app, click Google login, and pull up the Google login page;
2. Call up xxx app through deeplink, then open a new login page, click Google login,
3. Crash, the crash log is consistent with the above

I also have the same flash back, do you have a solution?

It also happens on my app. I'm using SDK version 8.0.0. Can someone please fix it? 🙏

Is there any update on it? Let us know if you need more info to reproduce it.

We have the same issue with our app on the latest 8.0.0 release! It's insufficient to bring crash-free users below our SLOs, but it's annoying enough to impact users.

We tried everything on our side to ensure that there are no race conditions and that the memory management on the related navigation stack is correct. Still, the crash continues, so it looks like it's coming from the SDK.

I cannot reproduce it, but it almost always happens right after a GIDSignInError.cancelled error, so likely when users cancel the flow.

This is also happening over here, if anyone found a fix
