I’m encountering an issue with my Unreal Engine project when packaging it for Mac in a shipping build. The application becomes unresponsive when switching to fullscreen mode, although it works perfectly in the development build on the same machine.
I have setup the windows full screen first:
And then applied the resolution:

I’ve set up fullscreen for the window first, then applied the resolution.
In development mode, the switch to fullscreen works smoothly, and the logs confirm the resolution change. However, in shipping mode, the game becomes unresponsive, and I can’t interact with anything. I have to force quit the game, but it takes an unusually long time to close.
I tried extracting logs for the shipping build, but nothing has been recorded, despite trying various methods.
I am using Unreal Version: 5.2.1.
Am I missing something about how fullscreen or resolution changes are handled in shipping builds in MAC?
