Had the same issue when I first install the Unreal Engine on macOS.

Rule of thumb : When working with Unreal on macOS do not use spaces in any paths.

Simply remove/install/re-install the latest Unreal Engine 5.3.x.  
Make sure your default folder install path has no spaces in it.

Word of advice, do the same for you project location and project names, do not use any spaces in these. This will save you more headaches.

I believe some of the Unreal scripts are not properly escaping paths and these are being truncated.
