Hi Toggl team,

I’m currently running **macOS 26.0 (25A5316i)** – the latest **beta 4** – on my Mac Studio (Apple M1 Max). The Toggl Track desktop app (version **10.12.0 (2978)**) **crashes immediately on startup** , every time. It worked fine on this same beta build earlier, but recently it started crashing consistently after launch.

I’ve tried reopening it multiple times, restarting the Mac, but the issue persists. The crash happens before the UI appears.

From the crash log, the issue seems to be triggered by an assertion failure related to Core Data:

```auto
less

```

`Exception Type: EXC_BREAKPOINT (SIGTRAP) Termination Reason: Namespace SIGNAL, Code 5, Trace/BPT trap: 5 Thread 0 Crashed: 0 libswiftCore.dylib 0x19a6ecab8 _assertionFailure(_:_:file:line:flags:) + 176 1 Toggl Track 0x100f3d8e0 ... 3 CoreData 0x18e8542d4 -[NSPersistentStoreCoordinator _doAddPersistentStoreWithDescription:...] + 668 `

It appears the app fails when trying to load the persistent store (`NSPersistentContainer`), which suggests it could be a corrupted local database or an incompatibility with the beta OS.

Let me know if there’s a workaround (e.g. deleting a local file or resetting app data), or if this will require a future app update for macOS 26 compatibility.

Thanks!

Thanks, it worked (solution 2) but I already have done it before (first time I installed macOS beta) and after that it was working there was that popup about sqlite database. This happened after that and after using Toggl for sometime. So it seems that this problem could reappear after database deletion.
