Texture2D.PackTextures causes mips 7-9 to turn pink when packed textures are of ASTC 4x4 compression

-

How to reproduce:
1. Open the “MipsBug.zip“ project
2. Open the “SampleScene“
3. Change the Platform to Android
4. Enter Play Mode
5. Select the “Terrain“ GameObject in the Hierarchy
6. Find and double-click the “Test Texture“ Texture field at the bottom of the Inspector
7. Change the Mip levels in the Preview in the Inspector
8. Observe the Preview

Expected result: All mips are rendered blue, white, or black
Actual result: mips 7-9 are rendered either in pink

Reproducible in: 2022.3.58f1
Not reproducible in: 6000.0.39f1, 6000.1.0b7, 6000.2.0a4
Fixed in: between 2022.3.58f1 - 6000.0.39f1

Reproduced on: Windows 11 Pro (23H2)
Not reproduced on: No other environment tested

Notes:
- The Android platform has to be active for the images to be in ASTC 4x4 compression format
- Black/white mips might also be a result of faulty behavior
