[iOS 14][Metal] Application stucks on splash screen and 'XPC_ERROR_CONNECTION_INTERRUPTED' error is thrown
How to reproduce:
1. Open the attached 'ios_long_startup.zip' project
2. Switch Platform to iOS in Build Settings
3. Build for iOS and open the Xcode project
4. Deploy Xcode project to an iOS device
Expected result: the application does not stuck on the splash screen and no errors are thrown to the Xcode console
Actual result: the application is stuck for about 30-60 seconds on the splash screen and 'MTLCompiler: Compilation failed with XPC_ERROR_CONNECTION_INTERRUPTED' error is thrown to the Xcode's console
Reproducible with: 2019.3.2f1, 2019.4.28f1
Not reproducible with: 2018.4.27f1, 2019.3.1f1, 2020.1.0a1, 2020.1.8f1, 2020.2.0b6
Reproducible with A10(X,Z) SoCs:
- iPad 9.7’ 6th gen (iOS 14.2)
- iPhone 7 Plus A1661 (Customer's info)
- iPad (6th generation) A1893 (Customer's info)
- iPad Pro (2nd generation) A1671 (Customer's info)
Not reproducible with:
iPhone 8+ (iOS 12.0)
iPhone XR (iOS 13.4.1)
iPhone SE 2nd gen (iOS 13.6 and 14.0.1)
iPhone 12 (iOS 14.8)
Notes:
1. Reproduction is not consistent, regression point might be incorrect
2. This problem only occurs on Metal
3. This problem can be reproduced in an empty project with the package "com.unity.visualeffectgraph": "7.3.1". Seems like it is not a package issue, for instance, it is reproducible/not reproducible on different versions using 7.1.8
4. Tested using Xcode 12 and macOS 11.0 Beta Big Sur
5. Full error message:
2020-10-05 12:30:10.230056-0700 test[581:33778] Compiler failed with XPC_ERROR_CONNECTION_INTERRUPTED

Hi warriors,
I get this on macOS (High Sierra) trying to run the VisualEffectGraph-Samples project in Unity 2021.1.24. This is an important issue to address since it blocks people from trying (and learning) the ShaderGraph in Unity.

In fact, there are many mistakes and they are frequent

Can confirm that this is still a problem. The culprit is the Visual Effect Graph and occurs when using older iOS devices with few cores (iPhone 6S, iPad 5th gen).
Problem occurs with Visual Effect Graph 7.3.1 on 2019.4.13f and 2019.4.22f. Updating to 7.5.3 does not help on 13f nor 22f.
You can reproduce the error by creating a new URP project and then adding Visual Effect Graph. After building to iOS with Metal the error will occur on older devices.
This error is preventing app to be launched on App Store. Please look into this ASAP

Have the same issue. It only occurred on (slightly older) devices (e.g. 7th-gen iPad) after updating to iOS 14.3 from 13.
Our project was originally Unity 2019.4.4, I updated to 2019.4.18f1 and it's still occurring.

Hi,
To add to this, I'm building on 2019.4.15f1 URP and this issue still persists on the devices listed above.
Thanks
