[Android] [IL2CPP] [Vulkan] App crashes on some devices when loading assets in coroutine

Vulkan

-

This case was created based on case 1345518 (a sporadic freeze). The freeze is fixed with https://ono.unity3d.com/unity/unity/pull-request/137731/_/platform/android/florian/fix-1345518-alt. When debugging this it's recommended to graft the freeze fix.

Reproduction steps:
1. Open the attached project "AssetLoadTest.zip"
2. Build and Run on Android device

Expected result: The cube in the Scene continues to spin
Actual result: After 10 seconds the app crashes with this stacktrace:
at libunity.vk::Texture::Create(vk::CommandBuffer*, vk::ScratchBuffer*, TextureID, TextureDimension, vk::ImageData const&, VkExtent3D const&, GraphicsFormat, int, VkSampleCountFlagBits, TextureUploadFlags, bool, bool)(Create:196)
at libunity.GfxDeviceVK::AcquireTexture2DUploadMemory(TextureCreateData&, TextureUploadMemory*&)(AcquireTexture2DUploadMemory:136)
at libunity.AcquireTexture2DUploadMemory(GfxDevice&, TextureCreateData*, TextureUploadMemory*&)(AcquireTexture2DUploadMemory:56)
at libunity.0x18f434(Native Method)
at libunity.AsyncUploadManager::AsyncResourceUpload(GfxDevice&, int, AsyncUploadManagerSettings const&)(AsyncResourceUpload:320)

Reproducible with: 2022.1.0a10, 2022.1.0b3, 2022.2.0a2
Not reproducible with: 2019.4.34f1, 2020.3.25f1, 2021.2.7f1, 2022.1.0a9

Reproducible with:
VLNQA00316, Samsung Galaxy Note10 (SM-N970F), Android 9, CPU: Exynos 9 Series 9825, GPU: Mali-G76

Not reproducible with:
VLNQA00288, Samsung Galaxy J7 (SM-J730F), Android 8.1.0, CPU: Exynos 7 Octa 7870, GPU: Mali-T830
VLNQA00001, Google Pixel 2 (Pixel 2), Android 11, CPU: Snapdragon 835 MSM8998, GPU: Adreno (TM) 540
VLNQA00225, Qualcomm null (SDM845 for arm64), Android 8.1.0, CPU: Snapdragon 845 SDM845, GPU: Adreno (TM) 630

Notes:
- Not reproducible with Mono Scripting Backend
- Only reproducible if ARM64 target architecture is selected
- Only reproducible with Vulkan Graphics API
- Issue can be reproduced in 10 seconds after app launch (this happens in 1 out of 4 launches) or after running app for longer times (usually over 30 min)

  1. Resolution Note (2022.2.X):

    Issue postponed to see if any users are seeing this outside of Unity. It's likely this is related to old drivers on a singular device. If we see any user votes or duplicate errors, we'll see what we can do when the bug reactivates.
