I developed a game using UE 5.2 and I followed the codesigning and .pkg creation process from this post How to create the proper .pkg file for deployment to the MacStore

I submitted my game to the testflight using Transporter and it was successfully submitted.
However when I download and install the game through test flight I am getting issue
