Last patch does not install on macOS

Hi folks,

Getting an error trying to update Path of Exile on macOS

"Path of Exile.app" is damaged and can't be opened. You should move it to the Trash.
This file was downloaded on an unknown date.
Cancel
Move to Trash

I am on an M4 Mac Mini running macOS Sequoia 15.3.1 (latest)

Please help!
