Crash : cannot create crypto

Steps to reproduce

Working on Tchap iOS Dev team.

Element 1.11.2 merged.

Sometimes, when running the app from Xcode directly on my device, I got this crash :

It doesn't happen on Simulator. There's no DB upgrade in the log on simulator.

On my device, I install over an old version. That's why the database upgrade is fired I think. But I suspect the DB upgrade could be the source of the problem.

Outcome

What did you expect?

The app to launch.

What happened instead?

The app crash in DEV mode (normal) because of an assert about "Cannot create crypto"
