Application crash when using Realm logger with 'all' log level

[gagik]

How frequently does the bug occur?

Always

Description

When using log level all or trace, the application crashes, likely when trying to log functionality such as

realm.subscriptions.update((mutableSubs) => {...});

It is possible with more testing and the changes in realm/realm-core#7934, the issue can be resolved on a core upgrade. Core needs to be updated and tested.

This was likely fixed with RCORE-2213, which has been merged.

Confirmed fixed with realm@12.13.1 (most likely by realm/realm-core#7934).
