App Crash Only When Downloaded From TestFlight

Hi everyone,

I'm experiencing an issue with my app, which is currently live on the App Store. I attempted to upload a new version, but the App Review team informed me that the app crashes on launch.

Sure enough, when I download the app via TestFlight, it crashes immediately on startup — I see a grey screen, and then the app closes after about a second. The strange part is that no crash reports are generated.

However, when I build the app in Xcode and install it directly onto my device via USB-C, it runs perfectly fine.

I've tried updating to the latest version of Xcode and followed the suggestions in this Reddit thread: https://www.reddit.com/r/iOSProgramming/comments/re2n65/app_crashes_after_testflight_download_but_no/

My app is a Unity game that had been working fine until now. There haven’t been any major changes in the latest update.

Could this be an Apple-side issue? And how is it possible that no crash reports are generated? Since the app crashes before it even fully starts, I don’t think it's a memory leak.

Any help would be greatly appreciated, I can give more info if needed — I’m completely stuck here. :/

Try using the same scheme used for local build for Testflight too and see if any issues.

Thanks, VoxelBusters Team

The error was different from what I though

I successfully matched the behaviour when clicking "product > clean previous build", and the error was due to AppLovin sdk missing. I resolved the dependencies and it fixed the issue. I don't know why there was no crash report, neither why this issue occured now while I implemented appLovin multiple version ago (without any problem)
