Crash on Terrain::UpdateSplatMaterials when removing Universal RP package with Terrain Lit material
How to reproduce:
1. Open the attached project from "URPpackageCrash.zip"
2. Open scene "PolarScene"
3. Using Package Manager, remove the "Universal RP" package
Expected result: Package is removed
Actual result: Unity crashes
Reproducible with: 2020.2.0b9, 2020.3.2f1, 2021.1.0f1, 2021.2.0a10 (Universal RP 10.1.0-12.0.0)
Not reproducible with: 2018.4.33f1, 2019.4.23f1, 2020.2.0b8 (Universal RP 7.0.0-10.0.0-preview.26)

Notes:
1. Removing terrain "SnowGround" from Hierarchy resolves the issue
2. Seems to be related to the terrain's material, only reproduces with "Terrain Lit"
