5.4.7 crash on launch with EXC_BAD_ACCESS in Realm.Configuration()

[hyouuu]

Goals

Use Realm normally

Expected Results

App can launch normally without crashing

Actual Results

App crash immediately on launch with EXC_BAD_ACCESS in Realm.Configuration()

Steps for others to Reproduce

Upgrade to 5.4.7 (Tried with CocoaPod and Dynamic framework installation; SPM installation fails which is also a weird issue for 5.4.7)

Code Sample

let config = Realm.Configuration(schemaVersion: 12)

Version of Realm and Tooling

Realm framework version: 5.4.7

Realm Object Server version: NA

Xcode version: 12.0.1

iOS/OSX version: 14.0

Dependency manager + version: Tried both CocoaPod 1.10.0 rc1 & Dynamic framework installation; SPM failed to install latest Realm (which was what I was using before 5.4.4)

Some context: I was trying to upgrade to 5.4.7 because saw it fixes realm/realm-dotnet#2025 - I don't use .NET but on iOS when accessing a filtered Results count property e.g. searchResults.count it would crash sometimes with Crashlytics reporting "Key not found", so I think it's probably from the same cause (please let me know if it's not). I'm seeing lots of crashes from that issue so please help fix this issue asap. Thanks!

@hyouuu Could you please provide us with a stack trace? If this crash is reproducible, could you boil it down into a small reproduction case? Thanks.

Actually just tried again and it worked (SPM) - guess the propagation of the new version has some undefined behavior before completing? Feels weird but maybe never mind :/
