UE 5.6: Can't import either provision profiles or certificates for iOS in Mac

When I tried to import my provision profiles in UE 5.6, it failed. I’m sure that everything like Bundle Identifier or Bundle Display Name is correct, since when I repeated what I have done in UE 4.26 everything worked as expected. The output log is as follows:

I feel like there’s something wrong in the source codes but I can’t find out. The log said that the libhostpolicy.dylib is missing, but where can I find this dynamic library?

I will appreciate it if someone could help me figure out it.

Where you able to solve this? I’m having the same issue after upgrading from 5.5.4 to 5.6.1. I can’t even get it to work in a fresh sample project.
The Mac is running macOS 15.6.1 (Sequoia) and XCode 16.4.

I was able to confirm that I could find the correct provisioning profile and certificate in XCode (opening up the .xcworkspace file for IOS, browsing to Game > [GameName] > [GameName] (IOS), and checking the Signing & Capabilities tab) so I figured I’d just try packaging anyway regardless of what the project settings says and, lo and behold, it worked!

Looks like all I had to actually do was to download and double click the certificate and provisioning profile per usual. I’m using Modernized XCode.

To clarify, I still get the same error as above, and nothing shows under Project Settings, but packaging still works fine regardless:
