Closing as "Won't Fix" because this is a simple "device out-of-memory" error that we are unable to fix. In the provided repro script, 1000 large textures are created and SetPixel / Apply is called on them. In a case like this, we would usually recommend the use of an additional "GameObject.DestroyImmediate(texture);" call (immediate after the "Apply" call) in order to clean the textures up once they are no longer needed. However: "GameObject.DestroyImmediate" does not actually immediately destroy the graphics API-sided memory. This action is, by design, queued onto the RenderThread. This means that some memory might not immediately be released and, as such, some devices might still simply run out of memory if more textures keep on getting created at the same time. In this case, it might thus be necessary to create smaller textures, or a smaller amount of textures.

How to reproduce:
1. Open the “ReproDiff.zip“ project
2. Open the “SampleScene“
3. Build and Run for Android
4. Press the “RegisterTexture 1000“ button
5. Wait for a few seconds

Expected result: Application does not crash
Actual result: Application silently crashes

Notes:

Issue reproduces with both Vulkan and OpenGLES3 Graphic API
This devices (VLNQA00335, Samsung Galaxy S20+ 5G (SM-G986B)) shutdowns and restarts instead of just the application crashing
