Editor crashes when painting tiles using the Tilemap Editor



How to reproduce:

# Open the user-attached project (
# In the Hierarchy select the “Grid“ GameObject
# In the Scene view press the “Open Tile Palette“
# In the “Tile Palette“ window that opens up press on the brush icon
# Paint a tile in the Scene view
# Observe the crash (if it doesn't crash immediately wait about a minute)

Reproducible with: 2021.3.6f1, 2022.1.7f1, 2022.2.0a17, 2023.1.0a2

Reproducible on: Ubuntu 20.04, Windows 10


# The issue is not reproducible on 2020.3.36f1 due to the “2D Feature” package being unavailable on the Editor stream, but going to “Assets/Tilesets/Ground“ in the Project view and selecting the “Ground“ prefab also crashes the Editor likely due to the same issue
# Not reproducible on a new 2D project
# The crash doesn't seem to produce any stack trace
