[Bug] App crashing when using useMMKVStorage hook

[CoryWritesCode]

Describe the bug
There seems to be an issue with initializing this hook.
This does not happen with 0.9.1 and it seems to be mostly an iOS issue. Hopefully that will help in narrowing it down.
I'm also not able to reproduce it on a debug build. Not sure why that is exactly.

For the time being I downgraded my MMVK package and it's working fine.
I have also noticed that it's crashing when we have users trying to "update" their app with the downgraded version.

edit
I found when clearing the library cache of the current user and then having them re-log in, all seems well. So it seems like there is something the old version of the lib is binding that the new version of the lib is not finding properly.

To Reproduce
Steps to reproduce the behavior:

1. Use the useMMKVStorage() hook

Expected behavior
It returns false if the value is not there.

Screenshots
App crashes with Exception in HostFunction: <unknown>

How I'm initializing the storage

Platform Information:

• OS: Seems to mostly be iOS related.
• React Native Version 0.74.5
• Library Version 0.10.3

@ammarahm-ed pinging only because this is a pretty intense issue

Facing same error on a small number of devices on iOS, I just upgraded to the new version. it seems to be related to specific storages not all of the storages on my app are affected.
Example when performing:
postsStorage.removeItem() an error is thrown with Exception in HostFunction: <unknown>.
I only experienced it on my m1 macos version of the app. although I am still getting crash reports from users devices on different versions on iPhone.
The issue seems to be gone when performing a reset to affected storages. example: postsStorage.clearStore();
An urgent fix for this would be appreciated.

Version:
react-native: 0.74.6
react-native-mmkv-storage: 0.10.3

I will look into this, would greatly appreciate if someone can provide crash logs from the release build

I don't know if this is helpful, this is the log from firebase crashlytics on user device.
its pointing to the removeItem() function when screen unmounts.
I experienced this same error once on my device, but was gone when performed a clearStore()
maybe someone else can offer a better crash log too.

We've got the same issue with very high prevalence, particularly when dealing with setting or removing our stored navigation state. Below are some stacktraces from our release build:

[ammarahm-ed]

Thanks @mmmoussa I am looking into the issue

[ammarahm-ed]

Hey everyone, can you try the latest version v0.11.0 and see whether it fixes those crashes. I was unable to reproduce this locally btw but I have made a fix based on some assumptions.

[mmmoussa]

@ammarahm-ed the app doesn't build on iOS with the latest version and the old architecture, due to the following issue:

[ammarahm-ed]

Hey @mmmoussa try v0.11.0. It should probably fix the build error.

[mmmoussa]

Tried v0.11.1 and it failed with a different error:

[ammarahm-ed]

It builds fine on RN 0.76. Let me try on an older version.

[ammarahm-ed]

Hey @mmmoussa Just released v0.11.2, can you try now. Make sure to delete Pods & build folders inside your project's ios folder.

[mmmoussa]

Build is now working on RN 0.75.4. Will circle back regarding the actual issue being observed.

[mmmoussa]

Issue is not resolved by v0.11.2

[ammarahm-ed]

Can you provide any native crash logs? You can find any native crash logs related to MMKV from Xcode -> Organizer -> Crashes. Are you able to reproduce this issue locally on your test devices in release or debug mode?

Can you try initializing your MMKV with new MMKVLoader().disableIndexing().initialize(). Simply add the disableIndexing() call to your builder.

Do this for MMKV instance that is not used by useMMKVStorage hooks. I am assuming your AppContextMMKV is not used in a useMMKVStorage Hook.

Also can you confirm if the issue is only happening to people who are upgrading the app. The new installs work as expected?
