App Crash from Firebase Remote Config
Description
The app is crashing immediately after opening, as indicated from Crashlytics as it's tagged under "Early crashes". The crash is happening randomly.
When the app starts up I have made sure that func fetch( withExpirationDuration expirationDuration: , completionHandler: ((RemoteConfigFetchStatus, ?) -> [Void])? = nil ) method is only invoked once to avoid any multiple calls
I am also using RemoteConfigRealTimeUpdate as well to fetch latest values whenever changes happen.
Can anyone provide me guidance on how I can resolve this crash as it's pointing to RCNConfigRealtime.m:449 and I have no insight on what's causing it

Hi @nik6018, could you share a sample app that reproduces the issue? Thanks.
Hi @rizafran I am unable to reproduce this issue every time and it's occurring in very rare occasions
@nik6018, could you share your full stack trace of the issue? Based on the stack trace you provided, it looks like there are missing UUIDs and the crashes aren't symbolicated.
