Hello! Thanks for submitting this issue. I'm curious if you're still running into this and if so, would you mind adding some repro steps or a recording of this happening? I'm unable to reproduce this on my end. I took a look at the two code snippets you sent and additionally when when the kScreenlockRequiredError is logged but didn't see anything unusual.

Hey there 👋 Sadly we couldn't reproduce this either as I mentioned I can't make Charles Proxy working together with the Google sign/login flows to manipulate that error.

We now have less occurrences of the crash but it is sill happening. Some stats:

Our peak of crashes happened on the 9th of October. In the last 30 days we have had 65 crash events affecting 22 users

Since this method can return a null string, would it be possible that this line of code and this handle the null value and replace it with an empty string ?

I made https://github.com/google/GoogleSignIn-iOS/pull/373 about this over half year ago. But it doesn't got any attention.
