Build Error: Ensure condition failed

[TTF_eric1]

Trying to get my project to build in UE 5.5.1 after migrating from 5.4.4. and getting this error. Since it all basically says Unknown File i can’t figure out what’s causing it. I have editor symbols downloaded but it still just says Unknown File.

Mac OS 13.7
Xcode: 15.2
UE 5.5.1

Having exactly the same issue after migrating my project rom 5.4.5 to 5.5.1, which currently makes cooking for IOS impossible.

Update: It turned out that cooking works again after disabling support for iphone simulator and Apple A8, but the I am no longer able to build lightning for my level.

Using iphone simulatior never worked on all UE versions, but at least the settings for it never produced these errors during cooking

This worked for me.
