[2021.3] Editor crashes on GetTransformAccess when undoing GameObject duplication

--

-

Reproduction steps:
1. Open any Unity project
2. Create any GameObject
3. Inside the created GameObject create a 3D Cube GameObject
4. Duplicate the 3D Cube GameObject
5. Undo

Expected result: Editor does not crash
Actual result: Editor crashes

Reproduced in: 2021.3.9f1
Not reproduced in: 2020.3.39f1, 2021.3.8f1, 2022.1.16f1, 2022.2.0b7, 2023.1.0a9

Reproduced using: macOS Monterey 12.0.1, Windows 10

Notes:
1. GetTransformAccess seems to be macOS related. Windows crash stack frames do not have it
2. Not reproduced when undoing duplication of an empty GameObject

First few stack frames (with 3D objects):
#0  Transform::GetTransformAccess()
#1  RendererUpdateManager::RemoveRenderer(Renderer&)
#2  Renderer::RemoveFromScene()
#3  Renderer::Deactivate(DeactivateOperation)
#4  GameObject::ActivateAwakeRecursivelyInternal(DeactivateOperation, AwakeFromLoadQueue&)

First few stack frames (with UI objects):
#0  Transform::GetTransformAccess()
#1  UI::CanvasRenderer::Deactivate(DeactivateOperation)
#2  GameObject::ActivateAwakeRecursivelyInternal(DeactivateOperation, AwakeFromLoadQueue&)
#3  GameObject::ActivateAwakeRecursively(DeactivateOperation)
#4  GameObject::Deactivate(DeactivateOperation)

First few stack frames (with light objects):
#0  Transform::GetTransformAccess()
#1  LightManager::RemoveLight(Light*)
#2  Light::RemoveFromManager()
#3  GameObject::ActivateAwakeRecursivelyInternal(DeactivateOperation, AwakeFromLoadQueue&)
#4  GameObject::ActivateAwakeRecursively(DeactivateOperation)

    It says it was fixed in 2021.3.12f1, but I can't find any such build in the Hub or Archive sites. Is it not released yet?

    Agreed, undo crashing is really bad. It’s not like you can save right before undoing when the point of undo is to *not* save the latest change. Please fix with urgency.

    My report was also marked duplicate of this. I'm using windows 2021.3.10f1 version. A very frustrating and crucial issue. Should be heavily prioritized and fixed as soon as possible.
