[Bug] iOS keychain access group crash

[timmac-qmc]

Library version used

4.64.0

.NET version

8.0

Scenario

PublicClient - mobile app

Is this a new or an existing app?

The app is in production, I haven't upgraded MSAL, but started seeing this issue

Issue description and reproduction steps

App when released onto iOS is throwing odd keychain errors which often result in total app crashes. The crashes only seem to appear when compiling in AOT mode. Very similar bug that was never resolved is here: https://github.com/AzureAD/microsoft-authentication-library-for-dotnet/issues/1562

Relevant code snippets

Code used:

authenticationClient = PublicClientApplicationBuilder
    .Create(_azureADConfig.ClientId)
    .WithAuthority(AzureCloudInstance.AzurePublic, _azureADConfig.TenantId) // Only allow accounts in the tenant to authenticate
    .WithLogging(_logger, false)
    .WithIosKeychainSecurityGroup("com.microsoft.adalcache")
    .WithRedirectUri($"msal{_azureADConfig.ClientId}://auth")
    .Build();

Console error:


QMCMobile[4349]/1#6 LF=0 copy_matching Error Domain=NSOSStatusErrorDomain Code=-34018 "Client explicitly specifies access group com.microsoft.adalcache but is only entitled for (
    "2KLF58357X.com.microsoft.adalcache",
