Reproduction steps:
1. Open the project attached by the user
2. Open "scn_gray_1_1" scene and enter Play mode
3. Continue forward to load another scene, then go back to load the previous scene
4. Repeat step 3 until it crashes

Reproducible with: 2019.4.9f1, 2020.1.4f1, 2020.2.0b1

First lines of the stacktrace:
0x00007FF641138418 (Unity) PhysicsScene2D::DestroyColliderIgnoreCollisions
0x00007FF64111D3E3 (Unity) Collider2D::Deactivate
0x00007FF63FD45148 (Unity) GameObject::ActivateAwakeRecursivelyInternal
0x00007FF63FD44FD5 (Unity) GameObject::ActivateAwakeRecursivelyInternal
0x00007FF63FD44D2F (Unity) GameObject::ActivateAwakeRecursively

Notes:
- Might be related to case 1231211, but that one is already fixed whereas this still reproduces on the newest versions
- I was struggling to test 2019.4.9f1, since the project package integration breaks after downgrading, but it did crash with the same stacktrace when trying to enter Play mode
