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

@ilyavelilyaev Thanks for the report. By any chance, does your project or any of your dependencies call sqlite3_shutdown()? This issue seems similar to past sqlite issues (#4278, #6039) due to sqlite3_shutdown() being called outside of Analytics.

[ilyavelilyaev]

@htcgh Thanks for reply!
I've checked our codebase and it looks like only Firebase has a dependency on sqlite3 and there are no calls to sqlite3_shutdown()

[htcgh]

Are there any other stack traces in the crash report that also use sqlite3?

[ilyavelilyaev]

@htcgh No, only com.google.fira.worker thread has calls to sqlite3, others don't

[htcgh]

@ilyavelilyaev If you can share any crash reports in their entirety or provide any other information like affected iOS versions, that would really be appreciated. My team will continue to look into this, but progress will be really slow until we can reproduce the crash.

[ilyavelilyaev]

@htcgh thanks for looking into this. Attaching couple of full stack traces.
endTransaction_stacktrace_3.txt
endTransaction_stacktrace_2.txt
endTransaction_stacktrace_1.txt

As for iOS versions - all versions are affected iOS 13 - iOS 17
Devices - it seems crash happens more often on older devices such as iPhone 11, iPhone XR, and very rarely on newer devices

I am also having a similar issue with a small number of my users. Here's the stack trace
