Crashes and ANRs on UE5.1 regarding ServerModels::FPlayerProfileModel::readFromValue

Hello there,

we noticed couple of crashes and ANRs on our android game, the error trace shows it's related to Playfab SDK and here's a snippet of the crash stack trace, what could possibly gone wrong here?

Keep in mind we're using GetPlayerProfile at some point, but the client version, I'm assuming we might access a missing key inside the response object?

Playfab SDK version:1.104.221205

The crash stack trace is related to PlayFab ServerModels. Did you call any Server API with ProfileConstraints? For example: Server/GetPlayerProfile, Server/GetFriendsList or any leaderboard query like: Server/GetLeaderboard. If so, you may check if you access a missing key inside the response object.
