--

-

How to reproduce:
1. Download and open the attached "EmptyWarmupTest" project
2. Build and deploy to iOS
3. Tap the device screen
4. Observe the crash

Reproduced with: 2022.3.10f1, 2022.3.12f1, 2023.1.19f1, 2023.2.0b16, 2023.3.0a12

Not reproducible with: 2021.3.32f1, 2022.3.9f1

Reproduced on: VLNQA00310 iPad Pro 12.9'' (iOS 13.4.1), iPhone XS (iOS 16.6.1)
Could not reproduce on: VLNQA00416 iPhone 13 Pro (iOS 16.1.1),

VLNQA00358 iPhone 12 (iOS 14.1)
VLNQA00359 iPhone 12 Pro (iOS 14.2.1)

Notes:
Running Shader.WarmupAllShaders() during the Start method does not crash.
Running it after application startup (by which I mean, in an update loop) causes the crash.
