How to reproduce:
1. Open the user's attached "RollABallTest.zip"
2. Build and Run on an Android device
3. Give the app Camera permission when asked

Expected results: The Camera's view can be seen in the app
Actual results: Instead of Camera view in the app it's black

Reproducible with: 2019.4.32f1, 2020.3.23f1, 2021.1.28f1, 2021.2.3f1, 2022.1.0a15

Reproducible on:

iPad Air 2 (11.0.3)

Notes:
- The issue is reproducible on Vulkan and OpenGLES3 Graphics APIs
- The code responsible for showing camera information and converting it to Texture2D:
p = cam.GetNativeTexturePtr();
im = Texture2D.CreateExternalTexture(cam.width, cam.height, TextureFormat.RGBA32, true, true, p);
im.Apply();
GetComponent<RawImage>().texture = im;
