Afaik we are using a standard approach for packaging with unreal automation tool, and not doing any runtime package loads atm. Here is the command line we are using to package game with:
RunUAT" BuildCookRun -project=“%WORKSPACE%/GameName/GameName.uproject” -noP4 -platform=%GameName_CLIENT_PLATFORM% -clientconfig=%GameName_CLIENT_CONFIG% -build -cook -stage -pak
If there is missing data, it seems to be somehow creating that data just prior to the crash since the game never crashes again on startup after initial just following first install of the game on steam.
The root of the issue seems to be related to using FText::AsNumber in a static function in EKeys::Initialize() when instantiating the touch key inputs.
