We are also experiencing this crash on 7.11. It’s currently our most commonly occurring crash. 😔
@paulb777 @maksymmalyhin We ran into the same problem，We used SDK version 7.6.0

@taschik We were able to work around this issue though I can’t say it was easy - I found this comment https://github.com/firebase/firebase-ios-sdk/issues/8024#issuecomment-860848817 Basically, it sounds like it’s caused by a conflict with sharing SQLite amongst Firebase and other code/SDKs that don’t clean up after themselves properly.
I referred the comment to one of our third party SDK providers and they were able to make the same code change mentioned in there, and that fixed the crashes (no updates to Firebase). It sounds like Firebase being mentioned in the crash logs is actually a red herring.
So basically, I had a punt as to which third party SDKs might be using SQLite, and sent them a “hail Mary” bug report which actually worked. Sorry I don’t have a more definitive workaround.
It’s getting to the point where I’m actively looking to rip out Firebase Remote Config because of the unacceptably high crash rate.
More than 20% of customers upgraded and not a single crash so far. I am afraid there is a serious issue in 6.34.0 because with that i had 10s of crashes in a day and in random places having “APMSqliteStore” stuff in common 😦
Same problem, had to rollback also…
