After a lot of research, I found out what the problem is.In the experimental features of Safari, enabling HTTP/3 crashes the SDK. I don't know if this is intentional or just that you don't support it yet.

Hi @mlorthios - We did a quick test weren't able to replicate the crash with HTTP/3 turned on. So its possible that if there was an issue originally (either on Apple's end or on the SDK side) it has been fixed. Since we can't reproduce at the moment I'm going to close this out. However let us know if you still experience the issue with the latest iOS SDK when HTTP/3 is turned on.
