  1. Resolution Note:

    Apple fixed the WASM bug in iOS 16.3. Our devs can no longer repro this issue on iPadOS and iOS versions 16.3 and 16.4, so we recommend updating to the latest iOS version.

    Safari 18.5 (20621.2.5.11.8)
    Happens in all games where URP is used. Hey, Unity team, you have a huge problem! Why are you ignoring it?!
