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

#12130

[rizafran]

Thanks for reporting, @smahajan28. I tried to reproduce the issue using the quickstart, but I'm unable to get the same error. Based on the related issue you shared, I'm wondering if your app or other dependency uses sqlite library?

[smahajan28]

We are using Realm as our database. I’m not sure if any other dependencies use SQLite. However, I haven’t encountered any crashes from other dependencies.

[smahajan28]

We’ve noticed this crash only after migrating from cocoa pods to SPM. We upgraded the Firebase SDK to the latest version in the recent release, but the issue persists.

[paulb777]

Based on this and #12130 There may be a race condition with Realm and their usage of sqlite3. A reproducible example would be helpful. cc: @leojaygoogle

Kind of same for me, but only with "Enhanced Security" capability enabled, [APMSqliteStore openAndValidateDatabase:] with empty details, MacOS 26, XCode 26.0.1, iOS 26, I am getting this crash only when I am downloading app from TestFlight

[JulianBissekkou]

Was anybody able to fix the issue? We have been seeing crashes of our app in production and without a fix or any possible workaround we are forced to remove firebase from our app since it's causing too much instability.
