I found a few problems with this issue:

I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.
This issue does not seem to follow the issue template. Make sure you provide all the required information.

Answer 2 · 2025-08-25T11:25:40.000Z

Faced same issue using flutterfire firebase/flutterfire#17649 (comment)

Answer 3 · 2025-08-26T19:35:46.000Z

Hi @anonym24, thank you for reaching out. I tried reproducing the issue using the dependencies you shared, however, I did not encounter any error. By any chance, were you able to replicate the issue? Can you share an MCVE to help us investigate the issue?

Answer 4 · 2025-08-27T09:54:24.000Z

@lehcar09 I believe we both understand that this issue doesn’t affect all users, and it’s not going to be easy to manually reproduce with the exact same dependencies. The issue is reported by Firebase Crashlytics for these versions, whereas previously it wasn’t present. So unfortunately, I don’t have anything more to share. As far as I know, Firebase can behave quite differently depending on user region and device models, so only their developers can really do something about it (e.g., try to reproduce the issue).

I believe the Firebase dev team must have crash reports from some apps on Google Play (maybe Google’s own apps like YouTube, Drive, etc.) with a large number of users. They could use the same dependencies in those apps and eventually encounter similar crashes in Firebase Crashlytics.

Answer 5 · 2025-08-29T12:35:31.000Z

This issue may be device- or version-specific, making it challenging to investigate. Could you provide the percentage of this issue's occurrence and the previous Firebase BOM/product version you used?

Answer 6 · 2025-09-04T18:00:37.000Z

Hey @anonym24. We need more information to resolve this issue but there hasn't been an update in 5 weekdays. I'm marking the issue as stale and if there are no new updates in the next 5 days I will close it automatically.

If you have more information that will help us get to the bottom of this, just add a comment!

Answer 7 · 2025-09-09T07:51:35.000Z

We are getting exactly the same crash when bumping Firebase BOM from 33.9.0 to 34.0.0 in an native Android app.

It impacted more than a hundred users during the last week, during the app startup.

We are using firebase-analytics, firebase-messaging and firebase-crashlytics.

The issue is not impacting Android 15 or 16 for us, an distributed evenly in lower versions: 29% Android 14, 27% Android 13, 22% Android 12, 16% Android 11.
Regarding devices: 82% are samsung, 12% Xiaomi, 5% Oppo.

Answer 9 · 2025-09-22T18:00:55.000Z

Since there haven't been any recent updates here, I am going to close this issue.

@anonym24 if you're still experiencing this problem and want to continue the discussion just leave a comment here and we are happy to re-open this.
