Editor Crashes when performing Undo and Redo after duplicating Game Object with LEGO Model Asset component

Templates

-

Reproduction steps:
1. Open the user's attached project
2. Duplicate "Platform" prefab from the hierarchy
3. Undo, then Redo, then Undo

Expected result: Pasting Platform is reverted
Actual result: Unity crashes

Reproducible with: 2020.2.0a16, 2020.2.0f1, 2021.1.0a10
Not reproducible with: 2018.4.30f1, 2019.4.17f1, 2020.1.17f1, 2020.2.0a15

Note: In order to reproduce instead of using the prefab, you have 2 other ways:
1: MENU_ITEM -> Import Model then proceed to step 2 with your new Game Object instead of the "Platform" prefab
2: Create a new Game Object, Add a LEGO Model Asset component, press "Reimport From New File", proceed to step 2
