Description
On the ios app that uses realm swift sdk, we see crashes happening when the app is opened after an idle time of around 1 day, when there are hundreds of changesets to sync. This crash doesnt happen when the app is opened after a few mins or an hour.
Attaching the crash log received from crashlytics.

Can you reproduce the bug?
Sometimes
Reproduction Steps
- Open the app. It does Realm login if not already logged in, then does realm sync and populates data.
- Quit the app and reopen again. - works fine
- Quit the app and reopen next day - crashes as soon as app is opened and doing realm sync.
- Until the changesets are all synced, the app keeps crashing if we open. Once sync is done it behaves normal until we quit and open after many hours.
